It seems so, yes. The ship I targeted definately did not disinintegrate, nor did it disappear much faster than before. It seems a lot of this damage is successfully mitigated.
You know, the biggest gripe that I have with Disintegration is that Vulkoras regenerates AM very slowly and it has a spammable 15sec cooldown PMS as its main killer ability. PMS drains its AM rapidly and without PMS the DPS of this ship is totally junk (with PMS it sucks as well, but a little less ). It is just that after 20 seconds into the fight, Vulkoras will not have 150 AM for Disintegration.
Do you notice the similiarity between Finest Hour and Disintegration? Both are life-savers, both now regenerate AM, hit points, both cause damage to a target. Yes, they do it differently, but the idea is the same - some ultra punch for 150 AM on a large cooldown.
Well, the thing is that Vulkoras doesn't have the punch of Kol (gun-wise mainly), doesn't have the survivability of Kol (both in terms of hit points, armor and the Kol's Adaptive forcefield) and doesn't have the combat utility of Kol (Flak burst against do-nada).
The Kol can enter the fight, use a Flak burst to scare of SC (or use an Adaptive forcefield to stay alive much easier) and proceed with gunning the enemies to some effect, saving those 150 AM while not being useless.
Vulkoras on the other hand is squishy, has no survivability enhancements and sending two PMS is all it can do if you want to use Disintegration in the battle.
So the problem of Disintegration is that it is a nice, ultimate damaging/healing ability with high AM cost to be used somewhere in the midst of battle, but it is on a ship that is completely unsuited to prolonged combat.
If something focuses Vulkoras, it will die - 15 seconds later if it uses Disintegration and nothing interrupts it. Moreover, between levels 1-5, Vulkoras is a crappy combat vessel with seriously lacking forward DPS. It is a great planet cracker, none dare deny... but killing planets yields no XPz. Killing planets while focused is a bad idea, partly because siege platforms constitute about a half of Vulk's siege capability and they are VERY fragile, MUCH more so than Sova's platforms.
Disintegration is just not made for this ship. It would be a great ability on Kol or on Kortul.
It just doesn't work with good ol' Vulk.
