Ah, so the truth surfaces finally. Face it, you just aren't as good a player as you might think you are. PW was just INCREDIBLY difficult in his infancy. CoP (original) difficulty was PERFECT, nothing was broken at all. None of those were broken. You wanna talk broken or downright insane, why not bring up pre-nerf Absolute Virtue? Though I'm fairly sure most recognized him as SE's untouchable baby and was mostly a joke boss never meant to be defeated.
The r50 dungeon difficulty is comparable to that of early CoP. It needs no adjustment at all except perhaps making it harder for ARC/CON/GLD setups. Though some people still prefer the easy route in hard content so that doesn't really bother me.
