what makes 1v1 pvp unbalancable are the god damn cooldowns. some specs down-right barely use medium to long-term cooldowns and some specs have i win buttons, relatively.
rogue: "damn i cant beat war, he pop retal/shield wall on me"
feral: "damn cant kill rogue, he pop evasion/blind/reset"
healer: "dam, cant kill mage, just iceblock/evocate/reset"
anything: "damn, cant kill paladin"
1v1: "shoot, whoever has cooldowns up wins."
shaman: "qq i lusted and used fire elemental qq"
edit: "damn, he popped AMS" surprise, surprise
