Boost battleship caps, they are underpowered and dont scale properly.
Lvl 10 battleship like Kol or they counterparts are lame at best. Sure, they can do trick or two, but they lack the fleet killing power.
Radiance used to have it, you could sink enemy fleet with well placed radiance and malice, now all the fincess is gone. All that matters is raw power.
Carriers are good because no antimatter, can keep them away from combat and have some antifighter or other useful tactical things like repair or economy jew.
All battleships fleet killing abilities are all but nerffed, kol is remotely useful as a glorified flak frigate against advent, but vasari bombers dont even care about the flak.
The only remotly useful combat cap is Marza, in my days i used to marzabait people with 3 marzas left right and middle. It is really all that combat cap shuld be, killing power against planets, a skill that can resolve battles in your favor if done right.
Most of the times, espesialy later on, caps are not worth the cost. I am bit eccentric player, because i can actually make some form of cap fleet viable, against semi retarded players... But if i really wanted to play serious, had good player against me and not for fun, 3 caps would be the absolute limit. After that it would be purely fleet spam and in your face rush.
Caps need love, it would be better if capital ships would be the factor that raises the fleet cap. Ever cap ship gives you 150 fleet cap for normal fleet. So you cant reach maximum fleet without 16 caps.
