first off, tell your friend to stop with Advent

they don't stand a chance against Vasari much anymore

second, armor, armor, and more armour, Vasari's secret weapon is phase missiles with walks all over shields but they are still halted by armor, which TEC has in spades

third fighters and flak are your friends, true flak is not as effective against bombers as fighters but they still can hurt them so feel free to invest heavily

Advent can beat Vasari, but it's going to be extremely difficult.  Basically you gotta flak spam and prey on the fact that Vasari have weak light frigates.  Honestly, this is an immensely challenging matchup now and I don't recommend it even for seasoned players. 

Your two options are flak spam and LRM spam.  Basically this comes down to using flaks to kill the bombers, or using LRM's to bring down the Skirantras.  Both have their challenges and counters.  As has been mentioned, hoshikos are your friend and a TEC player who isn't using hoshikos is just being silly.

Well, yes and no.  It depends on your goals.  If you are up against nothing but a fleet of heavy armor (hohos, flack, carriers) definatly target the hoshikos first. so they stop repairing things as soon as possible.  You see, if everything have heavy armor, you have the exact same modifier vs everything.... e.g. poor.

Now, if you want to, say, sink the capital ship (which is what EVERYONE wants to do.)  and your enemy has, say, 10 hoshikos... if you target the hohos first, thats a lot of tank you have to eat though before that capital ship loses its 20hull/sec.  

that 20 hull/sec is about (ish, depending on cap ship level and armor) 6 assailants worth of damage.  In other words, If you lose more than 6 assailants in the time it takes you to kill the hoshikos, then you have LOST dps on that capital ship than if you ignored the hohos and just ffed the capital ship.

it gets even trickier with say, lrm+hohos.   ya see, if you target the hohos, the reduction in damage of the tec player is negligible, while his lrms can attack your lrms without losing numbers.  you see, hohos are very beefy compared to a javillis, i mean, come on, a hoho has 3/4 the hp of a HC, for 2/5ths the fleet supply. (mind you, much more than 2/5ths the cost!!  56% using 4.5 rule), and your assailants have the same modifier vs hohos as heavy cruisers.

SO, lets assume the tec has tier 2 upgrades. for every hoho you kill, (not including repairs here) you could have killed...

and this is a little on the low side due to shield mitigation/time changes... but 2.1 lrms.

now, if you kill 1 hoshiko instead of 2.1 lrms, you have saved the tec player 500ish credit equivlants (using 4.5 rule)

now, remember these numbers are on the low side.  hoshikos are much better at repairing themselves than LRMS, so that skews things further towards the tec player, AND, that shield mitigation thing... it takes a significant portion ofthe javillis's hp to reach max mitigation, during which time you will be doing more damage.

and if you can do enough DPV to pop a LRM, (which is not hard), well, repairing doesnt do much then, does it.

so, wow, ya, thats intresting.   as odd as it seems, youll hurt the tec player more by killing javillis than the hoshikos...

SO, yes, I am saying dont target the hoskikos.  (that just feels so weird, to say that, it kinda goes against everything doesnt it... i feel like this should be tested somehow.)

Guys, skirantras should NOT be nerfed))) Or I would not win al MP with 16 Skiranras and ten dozen Lasurak)

As Advent, what if you do this?  If you know you have a Vasari opponent make your first cap a Halcyon with fighters and Telekinetic Push.  Then immediately build two military labs, research carriers, and make a couple carriers with fighters.  The Telekinetic Push will damage the bombers some and the fighters will help clean them up.  I suppose you could also make a few flaks.  If the Vasari guy makes more than two Skinatras, it will be more expensive for him to make the third Skinatra than it will be for you to make more carriers with fighters.  Also, research the Level 1 hull upgrade; it's cheap.  You can also research the first two levels of the increased damage for fighters.

I do think this can be countered if you anticipate it and plan properly.

both bombers and assailants have rather bad modifiers vs carrier cruisers.   equal fleet supplies of carrier cruisers and LRMS left in a gravity well together, the carrier cruisers will win.

It doesn't matter what kind of modifiers they have.  There will be enough of both around to kill it quickly and waste the large amount of resources and time that drone hosts take to be a threat.  Jumping carrier cruisers in and out of the well or repair is less effective due to the antimatter requirements for the squads.  We aren't just talking about 1 fleet of carrier cruisers alone versus 1 fleet of lrf alone either.  We are talking about skirantra being there too and possibly flak once the vasari sees the cap cruisers.  If you target the assailants with fighters, the bombers are left unfettered and will beg for your caps to die.  If you target the bombers, you will thin them out slightly but they will be quickly rebuilt while your fighters will be killed off by whatever fighter squads or flak he chooses to build and the AM on your cap cruisers run dry.  Once flak shows up, it forces a switch to bombers just to preserve any amount of SC dps.  Ever tried switching from fighters to bombers on carrier cruisers?  It is pretty painful.  You have likely ran your AM out jumping to the fight and regenerating battle losses and plus you have the build rate penalty for the combatted grav well.

Actually this is not what I suggested.  Disciples are ok so long as there are no assailants(read never).  Carriers are ok with bombers.  The bombers have to be in sufficient numbers to assure a kill before the cap jumps the well which is difficult to do in an early 5v5 rush.  You should definitely have more illums than carriers.  Illums suck at killing single targets but side beams can be doing damage to assailants or the cap.  Killing his cap won't do you much good unless you whittle away at the assailant spam as well.  Unfortunately for you, killing his assailants is less meaningful for the benefit of your cap because of the skewed paltry experience you get from killing assailants(20 exp) as the vasari gets from killing any other race but it has to be done.

I suppose thats enough talking more players into playing vasari for now as sad as that would be.  They are an easy win race.  They have so many advantages the entire game nowadays.  Good players from other races can give them a fight but its still an uphill battle for the nonvasari.

There is no killing flak quick with any lrf unless there is an overwhelming number on the lrf side.  Flak sorta counters lrf anyways so wading flak in would not be a bad idea for the flak heavy player.  A proper battle ball(using repulse) would prevent flak from getting close enough anyways.  Stationary strike craft are good when what you are fighting comes into range regularly(IE when fleets are slugging it out or defense of SB or any other stationary unit against bombers).  There are a few problems with a battle ball in these situations.  First off is teh assailant spam which goes along with the skirantra.  Assailants outrange push and they outrange illuminators.  A battle ball mostly staves off HC from doing their job.  LRF have long been the bane of a battle ball.  Also with guardians, they have big shields but practically no hull.  This is ideal for phase missles to kill since their whole benefit is to skip shields and vasari have phase missles on practically everything(including assailants, fighters, and bombers).  Even with repulse and a battle ball, it is still likely they can pop your cap before you can neutralize the bombers and lrf.  Repulse can buy retreat time certainly and actually enable you to kill a cap by keeping it from running if you have the foresight to position the guardian in front of any avenue of retreat.  As to stationary strike craft, it is situationally useful but far from a real solution to this problem.

I build 7 or 8 disciples at the start to help with militia clearing.  To get all the side beams firing, the illums have to be close range and as close to the middle of the enemy as possible.  You do not have to get directly into their formation.  A little bit away will do.  Sometimes it is advantageous to be right in the middle though depending on the situation.  Sometimes its even acceptable to run illums back and forth through the enemy formation to take advantage of side beams and the fact that turn rates are so slow that illums can fire the majority of the time but less so for other races due to theirs being all front.
