the root cause is the gear mitigation/critical number calculation.
I think the calculation needs to be adjusted so that new 80s have fun to play minis without being 1-shot. Many times, some low level demo told me POM really needed nerf. What I really believe it is not a class is OP, it is the gear which is OP. I will find hard time to catch Anatu demo and 1 shot him, oh yeah I wish!
