My priest is Shadow priest as a main
i still have Healbot loaded and yes i don't normaly switch gear for HC still with 4pc T9 i don't have to.
i have enough raw HPS that once im in Holyspec i don't have a problem healing an instance.

sure you will see me switching spec and drinking for 20s but that aint a problem.

i have been in a run where we actualy had a DPS warrior tank it wasn't a problem as long as he is DEF cap. i don't realy care. he have to keep aggro then i don't care i can heal a tank with 28k hp with ease so 28k and def cap then i don't care if not then i will ask if they are going to switch gear else im going to vote kick them.

Sometimes I think it's an honest mistake people make.. when you can do either role the default setting has each one clicked. If someone doesn't pay attention they can think they're queueing as DPS when actually they're picked to tank because they didn't notice it was selected. I had that happen once where the guy honestly seemed confused about why he was the tank and apologized and left the group.

That's just sometimes though, I'm sure it happens on purpose all the time, someone just expects someone else to pick up the slack.

Kroof you are a very lucky player. I have experienced a lot of people claim to be tanks and...well they aren't. Or they are beginning tanks, and click on the role in their DPS gear and are in WAY over their heads.

The one saving grace for me is that my Pallys are dual spec Ret and Prot, with Prot being my primary spec. However, I always queue for Pugs as Ret because I have run into this problem so often (and I tank for my guild, I like a break and the waiting for the instance to pop gives me a chance to scan the AH, do dailies, etc).

If I like the group, or the person that got in over his head (was in their ret gear), I will offer to tank. If they did it to beat the queue, no luck. I will wait it out (tab out and read WoW.com), etc. No way am I going to let them dictate how I play the game, nor am I going to let them give me an expensive repair bill.

Most of the tanks and healers I've run with have been at least semi-competent. The DPS, on the other hand, wow. I've been in a number of runs with casters who will cast about one spell per minute and maybe wand a little. I've been with melee DPS who will hang out in the back and never attack anything. I was with a warlock who just spammed Seed of Corruption over and over. It's kind of shocking how people can be that bad.

@kabshiel I spam Seed of Corruption on groups of trash mobs. As an affliction lock, it makes things deader quicker than my fire rain. Although if I find the tank is not holding aggro, I switch back to fire.

I've never experienced this either, and I tend to play hybrids that could take up the role. But please believe they would not be able to get me to do it for them. More than likely because I don't feel like waiting I would go to my non-dps spec, and then kick them out of the group, while we get a near automatic dps slot filled. I'm down for expediency, but ass hat won't be getting the perks of it.

@humperdinck:

I should've been clearer. They were spamming Seed of Corruption on a boss with no adds. And when I say spamming, I mean chain casting it over and over so it wouldn't even get a chance to tick.
