Are there any videos of a corsair fighting zakum or horntail using battleship? I have read the calculations saying that a corsair will out damage all when using battleship and homing/AH, but if the ship breaks often then they might not be that great at bossing. I realize that they can cancel bs before it breaks, but will that work enough to out damage nl's or even make them good at bosses? They will be getting hit a ton at ht and if they have to keep canceling bs and recasting it, then nl's might end up out damaging them.
