I still rather like the idea people had a few week ago to have deliverance engine additionally disable enemy culture-buildings in the targeted well for awhile(3-4 minutes would work).

It would enhance the deliverance engine's ability to accomplish it's existing purpose(enhance culture-attacks and ensure the advent fleet can get it's in-culture benefits for a key battle) without adding any whole new purposes(such as widescale conversions).

The problem is is that it doesnt shoot enough culture. I as playing advent loyalist one time, and I repossed a world in the middle of enemy territory. I quickly deystroyed all the strucures in the well, and built 3 culture centers. It was a 5v5 game and I was getting bombarded by deliverence engines yet my culture was still over powering them. Granted i had like 8 caps there and a titan. But the point is if they were shooting a planet that was surrounded by my own planets my culture would just dominate the culture they shot.

Like the OPs suggestion.

As it stands, people build maybe one Advent superweapon, two if they are hardcore.  No need for more.  It's like bringing spitballs to a fight when your enemies bring a skeleton key to the backdoor of your house and the other brings a pound of C4.

Pretty much what others have said. The problem with it is that every effect except the fleet damage buff is entirely negated when the planet you shoot at can overwhelm the DE's culture generation, which really isn't that hard to do. It doesn't matter how long it lasts if it's not doing anything.

All it has to do is disable local culture generation and thus always give the firing Advent fleet its own in-culture bonuses and it's suddenly fixed.

I don't think the ships converted should have a set number it should be a percent. 10% chance for each ship. that way you could actually possibly do some serious damage.

I was saying when you take over the planet you get all the structure in the gravity well, including turrets repair structures the works, except a starbase. That way the defense strucures there (if any) could possibly hold out till you get a fleet there to defend. 

No.  Not even the Kostura's original form was that powerful.

The dubiousness of the benefit was only half my argument- the other half is that all the benfits on tipping the planet in the world don't matter if you can't tip the planet.

At present due to gameplay constants and the nature of how deliverance engine works the deliverance engine simply isn't all that likely to actually cause a planet to revolt regardless.

And even if you did cause a revolt and instantly gain the planet:  A few stolen turrets and repair bays aren't going to stop the enemy from using siege frigates/capital ships to just bombard your newly colonized planet dead(doesn't take very long for an un-upgraded planet even if it didn't start from 1 HP like most colonizations do).   And your stolen static defenses are next in lien for demolition.

the enemy can see the revolt coming a mile away(allegiance loss is slow) and have a fleet stationed in the gravity well- and again if you send a fleet to prevent them from destroyign everything you take then you could have colonized the old fashioned way without this buff.

In essence against an opponent smart enough to have a fleet at a planet who's allegiance is dropping the entire benefit of this change would basically be "destroys static defense IF you can cause the planet to revolt"

And that's a very big IF, as there are abundant very efficient counters to  allegiance loss.

That said even just destroying fortifications would likely be OP when  it actually worked- in general an effect which is utterly unreliable but OP when it happens is generally very bad for game balance.  What is needed is reliability not an even more powerful but unreliable all-or-nothing effect.

So again I'd much rather have more reliable allegiance loss then a hail-mary added benefit for the occasional time Deliverance engine actually does tip a planet.  At present delivery engine's big problem is lack of dependability not the potency of the potential effect(the opponent losing the planet alone is already a large effect).  it make no sense to resolve this issue by further buffing the potential effect.

What you describe is a very cool idea, but it simply isn't giving the deliverance engine what it really needs: more reliability.  

Deliverance engine should by no means be a guaranteed planet flip, but it should IMO at least be reliable at

A). reducing the target planet's allegiance a bit(to cause some economic damage). 

B ). Ensuring the Advent has enough culture in the targeted region to activate their in-culture combat benefits

It needs something more then just ensuring the advent get their combat bonus and a little slap on the wrist for a person's economy. the Kostura cannon disables all structures in the grav well and creates a phase gate, and the nova does huge eco damage and planet damage. it needs to be a SUPER weapon not a meeeeehhhhhh cannon. 

Its not just that Serath I made a post about it but logistically it is very bad for a fully offensive fleet. If you go into full offense trees with the other races you get the Kostura and Novalith. With the Advent you need to go down the Hostility Tree AND the Harmony tree. This is a very bad mix.

The DE is kind of weak in my OP. I'd like to see it maybe, decrease tax income and resource rates, maybe slow ship and building production or even stop it all together for a period of time. That way it also damages the other players Econ more and more or less disables that gravity well.

You'd be infringing on the Kostura's territory.

I feel like their focuses should be the following:

Novalith: strategic nuke

Kostura: tactical weapon

Deliverance: psychological weapon

Honestly, what gamerlamb said earlier isn't something I'm opposed to.

Deliverance IMO should only affect allegiance and culture.  I feel like it should spawn strong culture from the planet that will dominate the target well for the duration and decrease the allegiance of the planet.  If a planet is neutral, I see no reason why it shouldn't be able to cap it.  These make it strategic.  Given that it is a mind-control weapon, I feel like it should have a minor boost to Advent damage while having also slightly debuffing enemy performance.

That said, if we decided to take the route where we made the superweapons truly super, I'd be comfortable giving it the capacity to cap enemy ships/structures, though I'd be hesitant to do a flat percentage.  Perhaps instacap 10 frigates plus 5% of the remaining ones.

Following suit, on the Kostura, we'd have to make it even more powerful than it was originally.  Completely disable enemy ships and structures and deal massive damage to all of them.

The Novalith then should be able to bomb a planet down a level.  Terran>Desert>Asteroid>Asteroid Field; Lava/Ice>Asteroid>Asteroid Field and make it uncolonizable for a very long time.  Perhaps even have ships in the gravity well receive 3-5 DPS from radiation.
