So, what builds are you using that seem to work? I can't seem to get past round 7. Best Build has been all ranged with 2 healers. Everyone has a stun. Any other build seems to die out around 5 for me.

Why do ranged characters run TO the melee and then back away afterwards? I can't count the number of times my acolytes and mages get splattered because they run right into a cleave shot from the enemy while running RIGHT INTO their melee companions. It doesn't seem to matter how much I buff attack range, because they invariably just run into melee first....

the acolytes keep getting stuck in the center of the battlefield in between waves when all the other guys are running back to the starting position.

Just that. Permadeath feels too punishing.

why i cant promote doomsayer even it show promote button + enough gold
