So I've tried Ret in PvP, Warlock main, and I have noticed that the spec plays like shit. The burst is mediocre, both my DK and Warrior alts have much higher burst, the self heals are terrible (25 - 30k FoL and only being able to do it 3 times in a row while bubbled), between CDs the damage potential seems to be the lowest of any of the classes I've played, there just seems to be nothing going for the spec. It seems based around group utility, which is fairly bad as you could just bring a Holy Paladin and gain the same utility. It also doesn't help that it seems to be that Ret is completely incapable of doing anything alone, if you're the last one alive in arena and are fighting almost any other class played by an equally skilled player, you lose.
Is it just me or is Ret one of, if not the, weakest spec for PvP in game? There just seems to be nothing going for it.
