yeah but that always happens... before it was palemasters, ice savants, remember the monster, batman? etc etc etc
the "power gamers" do this all the time, someone find out the latest broken ability before they nerf it (like we have now with furyshot or master blitz during the entire quest, have no doubt they will nerf those sometime in the future)
fit them in a build and play with it while it last...
if we HAD to be on those builds to complete any EE quests i could see the system as being broken, but you rly don't need to...
