When I say a berserker isn't up to snuff, It's because I've played two.
Fine, you CAN play a berserker and it's POSSIBLE to win vs a Warrior. I've done it. However the problem is that it was far too hard for what it should've been.
When I play a class and can only successfully beat people far less skilled than me in PK, I see a problem.
People are saying they've played successful Zerks. I haven't seen them, or perhaps I just didn't consider them PK successful. 
RE: Emp: Yeah? Go ahead and prove your zerk point. I'm going to laugh when you fail. And the Harden Up philosophy refers to full loots and PK in general, NOT unbalanced combinations. Btw, have I ever said harden up? No. I'm not a fan of full loots and I find a player who constantly full loots only does it to make up for a lack of ability(keeping your enemies unequipped. It's much more challenging when all your foes HAVE eq). It's not a philosophy I prescribe to, I just found it funny when Eshaine quoted LA which is why it is my sig.
Should I make a Mino zerk/warrior and abuse something just because it's there? Maybe I will. Once I get back from NZ and have a proper connection.
There have been at least 4 ogre/rangers that were unbelievably buff in PK. Were they all the same player? I doubt it. I've been up against these ogre rangers in VERY buff ranger killer equipment/classes. I had absolutely no chance in PK and it was not player skill that was the "big problem."
I could have only won had they made a glaring mistake for me to capitalize on.
