Fighting the mobs is more exciting and dangerous than the Claw (and more rewarding), honestly. Excitement/danger/reward is a pretty good recipe for FUN. Especially as a melee based class that can’t stand on the side during phase 2 it is much more enjoyable to kill pillars and dance with the god status champion puppy and icebrood. Considering the fact that all damage aside from the adds is proximity based there is really no excuse for dying outright.
Unless you’re a guardian there is really no reason to be smashing your head against the ice wall til it breaks. Every other class has damage at range that should out class the bazooka.
