Just got Grevious...

He's pretty garbo as any skill that he has gets outclassed by other droids. He has the highest basic damage but even that is outclassed by an 88 who's enemies have a buff or two. His laugh is just horrible as it not only wastes 1 turn, but what should be two if you're on a droid team.

I'd keep on farming him if I were you as he is just screaming rework
