Ninja: Walk in shadow.

[Leonus]

I'd be willing to bet that ninja buffs won't stack with multiple ninja's in the party, so the other ninja's usefulness would be cut down. There probably won't be any need to have more than one in a party.

Ninja will have its own attack increasing buffs more than likely on top of BfB. I personally think that the only loss ninja took from not having brd CC is misery ' s end. If that was even gonna be cc'able.
