I think part of the reason is that ps4 is a pretty big part of this games playerbase and majority of them have absolutely NO clue how much dps they actually do.

They think their hot shit when in reality they are doing less than that 'meh' geared paladin in shield oath. So they keep doing what their doing, thinking it's all good.

This is only part of it. There are tons of different reasons for this happening.

Basically I'll leave it at "bads will be bad"
