I always wondered what would happened if the GRG was just a regular weapon and not an AM ablity. I would assume the Kol would be sniping capital ships and maybe starbases like nothing especially after its weapon upgrades.
Haha indeed.
Actually, fixing Kol is easy and has been discussed extensively. The most consistently agreed upon problem with the Kol is demand on its AM reserves. Rather than grossly buffing the amount of AM it has, which would be out of character in relation to the other Battleships, I favor the passive ability solution, which is much more in line with the character and feel of the Kortul & Radiance Battleships.
I would make Adaptive Forcefield a passive ability with a slight nerf to its effects to compensate for the lack of AM requirements. Something along the lines of the following
Effects: L1- 10% Damage Reduction, 15% Phase Missile Block
L2- 15% Damage Reduction, 20% Phase Missile Block
L3- 20% Damage Reduction, 25% Phase Missile Block
This would greatly balance the Kol making it have a true niche role of damage sink/Anti-SC. GRG would still be it's weakest link but I would feel OK with the Kol in relation to the other Battleships with this change as they would each have a passive, weak active, strong active and strong supreme.
