This is by no means a good counter to corvette rush, because corvettes are available at the very start of the game and starbases are very expensive, so people can still easily overwhelm those with a massive amount of corvettes early on.

Corvettes just need to be nerfed in some way. Possibly the best solution is to just remove their speed advantage, since then they would be more easily destructable by light frigates and other kinds of ships, while still remaining useful by being very cost -and damage effective.

I always win against corvette rushers. I usually play TR and dont put money into a fleet without first discovering what the enemy is spamming. If corvettes as it usually is... flak easily wins and with two combat caps i quickly take the upper hand. I dont really see any major problem with corvettes except that fighters are slower than them which should def. be changed.

If Stardock had balanced them like so many experienced players had suggested the little sob's wouldn't be so OP.
