Level 143 Corsair Soloed Zakum

It's not that simple. Since a Corsair's Battleship breaks by taking too much damage, it's advisable to get hit by little things so it takes as long as possible to break. Also, since there's Homing a Corsair can sit in a sea of mobs and not worry about not hitting the target.

I know that, but surely sitting there for 90 seconds is worse than clearing out the mobs and actually doing something.
