Truth is PF consists of good people, medium people and bad people. The HP of the adds in m6s was chosen on a level where good people would clear it, medium people did not and bad people will outgear when they reach it. That's why it feels so bad, that's all, PF has a full range of these people and the truth is the slower you clear and the slower you are in general even time wise when you start the higher chances you get to meet bad players. Someone said it well to me: after the initial phase of good players whether you prog or not in PF is pure luck and it's just like that. Eventually you have to face the reality that your skill only can go so far without fitting people.
