This is pretty much what capital-type armor already is:

Anti-very-light (flak) : 25%
Anti-light (fighter) : 50%
Anti-medium (LRF): 75%
Anti-heavy (LF): 50%
Anti-very-heavy (bomber): 60%
Composite (HC): 75%
Capital Ship: 100%

The only ones that stick out are the light frigate (which is too fast a unit to buff versus capital ships) and the bomber (which got a much-needed nerf in that department quite recently).  Everything else is either strictly anti-light (flaks and fighters) or deals 75%. 

It's not damage modifiers that make bombers so dangerous in the late game.  It's a combination of their speed, focus fire potential, immunity to regular attacks, and ability to synchronize attack runs that make them so deadly.  Big targets like capital ships and starbases can really get pummeled in the first few seconds of battle, with little recourse if you don't have the right capital ships in formation.

Who says Titans won't have antistrikecraft weapons? Further I suspect Titans will be tough enough to survive several passes from any number of bombers that players reach in a normal game. And if its really necessary, I suppose they could reduce the modifier from bombers so that any fleet of frigates would be a valid counter. Point is I doubt the Devs are going to let bombers be the counter to Titans as well.

Titans are large enough to be a structure, have them take structural damage instead .  Titans should be able to outrun Vasari starbases so that the vasari .  Considering vasari's late game advantage to movement, being the most vulnerable to a titan attack could be tweaked to make a good balance.  Vasari might have a tougher time getting a starbase in close, but then they have phase missiles on their bombers so no worries, they will still be OP in the late game.

Also to be fair, the vasari always had a titan, it just had to be built in the gravity well.  Its called the vasari starbase.  Lol.

I'm not too worried on this one.  LRF cannot attack while kiting, so even if they do outrange the titan significantly it should still be able to close the distance pretty quickly.

The problem is that if multiple strike craft hit simultaneously, their damage is applied and then mitigation is adjusted.  This means that if you synchronize your attack run, everything hits at minimum mitigation.

As I said, my fear is that Titans will be weak against bombers.  There's no indication yet as to whether titans will have anti-strike craft capacity.

As I mentioned, bombers can sync their attack runs to hit at lower mitigations.  This means that no matter how you cut it, those late-game first-strike bomber attack runs are going to outdamage anything else quite handily.  Maybe it won't kill the titan, but it'll probably leave it heavily damaged.

The only significant difference this would entail is that they would be weaker to bombers.

Adjudicators are pretty worthless against single-targets to begin with, so this is pretty much an Ogrov-specific buff.  Depending on how TEC's late-game balance plays out in Rebellion, that might be either reasonable or completely unwarranted.

If it's truly instantaneous, then it should all go through, though it's always going to be staggered slightly in practice which would probably explain your results.  You should be able to get some of the bombers to hit at the same tick, but not all will...

Just did a test using about 15 light frigates. I lined them all up and had them fire at a neutral LF so they were oriented correctly (so they would fire instantly when ordered), then told them to stop firing, waited for the enemy frigate to repair itself (took a while), and then had all my LFs fire again in a single volley. Assuming the theory that mitigation takes at least a tick to kick in, damage was significantly less than it should have been - one volley from one frigate did 41 damage, one volley from each of 14 frigates firing at once did 364 damage when it should have done around 574 damage. A huge difference.

Therefore, I'm pretty sure mitigation increases are calculated after every hit, inside of a tick (or something with an equivalent outcome).

Test it yourself if you want. It's really simple to set up.

I don't get the difference. Both units fire at once, then have a weapon cooldown time of a few seconds, then are able to fire again, and both are backloaded...

Seems to me there would be some sort of countermeasure you could build to help defend against the Titan.

Corvettes are being introduced with Rebellion as well, so they might be a counter or have some role in this.

bombers are just small fast ships but if you get a swarm of them, they can be trouble.  but who knows?

Small, fast, and high damage.  They're either the highest or second-highest overall damage dealer on a per-command basis, depending on which faction we're talking about. 

I'm sure that's going to be the main focus point of the beta, to make sure they aren't that over powered. I'm willing to bet that they'll take so long to deploy the vast majority of multiplayer games will have already been decided, but it certainly is a concern.
