As evidenced by Grimbold:
Ret has been more or less balanced in organized PvP several times throughout WotLK and even in Cata before the WoG nerf, but for some reason the devs insist on balancing ret around unrated BGs and sub-1500 arenas, where opponents are less likely to take advantage of our weaknesses against kiting and dispels, and where our lack of offensive utility is less of a problem- not having a snare isnt as much of a big deal when your opponents are too stupid to kite anyway, and even before Cata we could "interrupt" bad casters by just running through them.
It just pisses me off that the way the devs "balance" ret completely contradicts the way they balance other specs.
Ret is OP in low rated arenas but average in organized PvP? TO THE GROUND!
Mages OP in low rated arenas but average in organized PvP? Its fine l2p.
Ret is using its resources to heal instead of DPS? Herp derp we can't be having that, never mind the fact that healing has pretty much always been ret's only strong point compared to other dps specs.
DKs are using their resources to heal instead of DPS? Cool story, bro.
Seriously, what the hell.
Pretty much. And later on, I'll add in the links from blue responses to add to the sheer silliness of it all.
