First, I'd want to hear how a capital can survive against focus fire from 30+ heavy cruisers, other than Dunov/Overseer spamming and microing.
A ship outnumbered, outgunned, and overwhelmed is
going to die. That's not an issue. You are
expected to take casualties in massive scale battles.
No existing game mechanic has not fixed this problem. The solution, as I suggested in other thread, is to make access to high-level capital ships more convenient in late game.
I probably wasn't clear in my post. To restate it in a better way:
If low level caps are hurting your fleets late game, why aren't you using the training system?
