we have done that. many times. and we will continue to do things like that. however, creeps have strength in numbers. freeps can come out in a group of 3 and if they are well coordinated can wipe the floor against 6 creeps. as creeps get their DP and infamy they will get their stuff together. now that several of us in the tribe are siggy and have our passive and resistances i will promise that we will continue to fight without relying on a "zerg".
if you had not noticed, our tribe has not been afraid to die at the risk of a kill. in my eyes i will charge in for a death in an attempt to get 1 kill every time the situation arises. we have been trying to coach some other creeps into new pvp strats as well. however, when freeps swarm ec, take sb, and park on the lawn, you cannot expect a different result for those creeps other than to turtle in the keep and wait for numbers.
