4V1torys team also works. Shaman, LoL, charolette and the major. I only ran it seven times and won all on auto. Only losing charolette once on the last wave which didnt count to ward the acheivement.i didnt watch them, but I think the major was the key to victory. I may have been lucky and havent got caught in the doggy trap.
Many still dont have the major which he has been invaluble many times since. For many it is becoming a real choice on who to go after while falling behind.
