"Ok, so he kills stuff in combat! And he shoots stuff with Plasma! Isn't he just great? Well, no, he isn't, because you can't take Kroot any more. Oh, and it's a 3 Broadside cap for you. And 1 Hammerhead. And 1 Piranha squadron. Doesn't look so good anymore, does he?" He still looks good to me. I'm undefeated with him so I guess he works, and I have beaten two Abbadon armies using this strategy. So, Yes I will take a Tau hero who can kill stuff in CC and has the addition of extra Ap 2 plasma shots.
