My group keeps getting matched with guys that have 4 sets of war elephants in their stronghold. Problem is they are almost immortal. It takes 10 mk6 fighter attacks and ground troop attacks to kill them. My war elephants only have around 15,000 hp. So is this cheating? Infinate elephants. 4 sets for 20 bases. That's 80 donations. Plus they seem to be immune to planes.
