The problem with this thinking is that Ninja is now considerably more difficult to play properly than any other DPS. It takes a lot of work to maximize DPS, and even then you still fall short. Trick Attack alone doesn't make up for it. If it's going to be at the bottom for personal DPS, then it needs more or better utility. If a heavy-hitter DPS can deal more damage than Trick Attack is able to offer, then there's legitimately no reason to even play Ninja.
