Re: Nerf it all! -how to create a game that's fun for the losers-
There's nothing "arguably" about that.
They're versatile classes - however they are never ever utilized in a "versatile" way. They are either DPS or Healing.
Further more, in the group-setting of WoW there's no "king" playstyle - without tanks everyone dies, without healers everyone dies, without damage dealers everyone dies.
This translates equally so to Perpetuum, without DPS bots everyone dies, without EWar bots everyone dies, without Repair everyone dies.
Comparatively, what you and the 4-5 loud fellas are asking for is that Arms/Fury Warriors should be the "ultimate class" and everyone else who happens to have picked the "wrong" class should be relegated to supporting the chosen few who happened to have picked the "right" class.
It's flawed, egoistic and selfish logic, revolving around metagaming the Developers to nerf everyone else who doesn't play "the right way" - otherwise known as "your way".
