Non-Battleship Corsair?

Saying we're useless at bosses is a little extreme.. my dps on single targets=that of heros far beyond my lvl.

lol. You're funny. Just because you may have outdamaged a higher level Hero, doesn't mean anything. He might have had much worse gear than you, and if you were both appled, that tips the scales in your favor.

Lets look at some simple numbers here.
Brandish does 988% damage/swing
988*1000/690 = 1431.9% DPS

Demolition does 3200% damage/attack
3200*1000/2340 = 1367.5% DPS

Not only that, but a Hero will generally have a higher damage range than a Bucc (Buccs have a better multiplier, but much lower attack. That's why apples help them nearly as much as NLs), and unlike Demolition, Brandish can be used all the time. Not to mention Stance.

Buccs are good SI and TL mules, and they can also chip in to the damage done. That's it! They won't KS any other attacking class (except maybe Pallies if they're appled) provided there isn't a massive difference in gear.

Don't get me wrong, I think Buccs are cool. Tons of people enjoy them regardless of how much damage they can do to a single target. Time Leap is incredibly helpful in boss runs, and they can train quite quickly. But that won't change the fact that they're a subpar damage class at best.
