BattleshipCannon Vs Demolition

Check facts.
Uncharged Assassinate+DS spam is 600%x3 or 1800% damage, and takes 2 seconds. 30 a minute, so that's 54,000%. Uncharged Assassinate+DS spam.

Add in Boomerang Step and that's 600%x3+1000% = 2800% in 2.7 seconds. Damage/time = 2800%/2.7*60 = 62,222% a minute.

The disadvantage to Shadowers at bosses comes from the fact that there aren't any supports that help them much. SE has a minimal effect on those high damage %'s. Time Leap only gets you a few more seconds of Smokescreen. And they don't have any self damage enhancers such as Combo, Venom, Expertise, and so forth.

Assassinate + BS is better than SB -> SB -> BS right?
