The attacks are going to happen anyway. Saying "But you have to pay for the weapon!" is silly. I suppose you could run a 90-point battering ram around the board, but I have yet to see anyone really do that.Why's it broken in Epic? You're paying for those crew slots and those attacks - is it significantly better than taking three or four decked out Falcons?
If you think being able to triple-stress ANYTHING for 2 points is balanced, we'll just have to disagree. I honestly haven't played the CR90 enough to know what the opportunity cost is like, but that would scare the heck out of me.
Yes, those attacks are going to happen anyway, coz you've spen those points on the Tantive. You could have taken a bunch of YT1300s and achieved pretty much the same thing couldn't you? Similar number of attacks, similar number of crew slots and far easier to line up the shots.
I haven't tried, but I don't think it'll be right easy to pull off on a Corvette anyway. Just getting a ship in arc for your primary and secondary weapons can be tricky, and you've got to worry about being at a single, specific range as well, with no way of adjusting your position.
