Nebitt vs. K2-SO in droid squad

Buckbeak

I've got a classic droid squad line-up, HK(l), IG88, IG86, Jawa engineer and Nebitt. I've got K2-SO at about the same power as Nebitt, 7 star, gear 8 and I'm pretty impressed with both of them but K2's got a little more wallop and a little less taunt till I die. I was wondering if anyone has any thoughts as to if K2 would better in the long run.

I'm hoping for an arena squad as well as a damage dealer for P2 of the tank raid.

K2 for arena, nebit for raids. And where is your b2?????

Buckbeak

He's taking turns with Nebitt. Seems better for GW than arena but he's about the same power. What lineup do you prefer?

B2 doesn't seem to useful in the raids. at least not gear 8.
