Calm down holmes.
No one is telling you to quit. I'm saying the DK nerfs are justified. I don't think I'm elitest or class envious. I have a 73 DK I've done some tanking on, I didn't like it. How am I being elitest? Someone who doesn't agree with you == elitest? Would you rather people just reply "QQMOARDKNUB" or something along those lines? Feral Druids were relegated to OTs in BC because we had no way to effectively AoE tank. Some druids managed ok without it, most didn't. I fully support balancing tank classes to where any tank class can MT. Hell, thats the reason I'm a MT now. I have no gripes with DKs MTing, by all means. I wouldn't want to be relagated to just an OT position either.
I agree with Fur, look at the other tank classes history, you have no room to gripe at all. It could have been much harder. Nerfs suck, but shit happens. You should enjoy what Blizzard has learned and didn't screw up with DeathKnights that they DID screw up with previous trials with tanking classes.
A class that can tank really well in any spec, DPS really well in any spec, AND PvP really well in any spec isn't OP? /facepalm
Edit: I went looking for one of the original announcements that talked about DKs as an OTing class. I can't find it because cardplace gives file not found errors in their archive before August. Regardless what made that stick out in my mind was they were saying that so all the other tanking classes wouldn't be up in arms about ANOTHER tanking class. But hey, 4 tanking classes that do really well = win for raiding guilds. But obviously WoW isn't balanced around raids.
