Kol: Increase the power of GRG, but do not make it bypass shields. If any ability in this game deserves to do that, its Disintegration on the Vorkulus. I would recommend up to a maximum damage of 1600, but leave the AM cost the same. That way the FF+GRG combo still has value.
Flak Burst: It once was the best thing the TEC had against SC. Now though, a Sova can do just fine. That means that this thing needs a buff. I recommend a damage buff of 40% and a range buff of 20%.
Adaptive Forcefield: Dead on. This ability is perfect.
Finest Hour: Not the best final, but its good and just about makes the Kol immortal...
Stats: I'd say that a generic buff of 20% to all regular stats would be perfectly fine.
Kortul: Just standard stat boosts will do it. No big changes are needed here, as they fixed most of the issues with it in the latest patch..
Stats: DPS boost of 25% (would come out to be a very nice buff with PS) and a shield/hull boost of 10%.
Radiance: Once again, just fine minus a couple things...
Animosity: I have no idea what to do here... But it does need a purpose...
Stats: I'd say a 25% shield boost coupled by a 15% damage boost would be good.
