Why are Healers allowed to be insanely overpowered?

[Gor]

The problem, as you said in different words, is DPS are too lazy/too stupid to maximize their classes and plan their approaches

^ this. i see alot of people who just dinged 50, still in quest gear and only parts of their 50 job gear, or didn't even bother to get at least ilvl 80 gear, or come in with ilvl 70 PVP gear into FL expecting a carry. or tanks that gear and spec vit. or goons who DR out stuns because they want to dragonspine dive the healer to death before the tank even has a chance to reach the healer. you have enough of those kinds of tards on your team you're not going to put a dent in any geared healer with even a tiny bit of a clue how to play the class no matter how many of them are on it.
