A corvette (replace with any other class), can have approximately 10 viable builds on 3 different ships. All of them need a more or less different counter build.
Now imagine playing a Tac, which is the best counter class for most corvettes imo. I'd need roughly 3+ builds to counter. I have my Koschei, which is full heal (duh), that leaves me with 2 counter builds. How am I supposed to counter all those different kind of corvette builds on just 2 ships?
It's easy to build an all out offensive build, but countering those in every single game is nearly impossible, given you have faced the grindwall and actually got enough ships to counter.
We need multiple builds per ship back.
