High DPS =/= Skill

So, I was just in a PUG with a few people running Zul'Aman.  Now first, off, I will say that ZA is not my favorite instance.  PUGging ZA makes me edgy, as people tend to go balls to the wall in the hopes of getting the bear mount, and when they don't get it, it tends to fall apart for various reasons.  I've been doing better with that shit, but...

This time around, I had a mage who was decked out in all sorts of high end gear, and he thought that I should be kissing his 42k DPS ass.  After he bit the dust during the Halazzi fight (failing point: not using some of that leet deeps to down the damn lightning totems), he proceeded to ask me if I was having some problems keeping him alive.  I told him that obviously I was, because he was taking a shit-ton of damage and that he should probably try to concentrate on downing the lightning totems to make it easier.  After claiming that it was "the melee's job to take care of totems," he proceeded to nag me about putting up Blessing of Kings instead of Blessing of Might.  I would have been open to suggestions had he not been such a dick about it.  He continued to be a dick for the rest of the run, posting DPS meters after every pull and at the end, he made the statement, "healer, you may have gear, but you don't have skill."  The tank whispered me and said "don't listen to him, you did good."  I told the mage that he may have gear as well, but he was the one who really didn't have skill.  He retorted by posting the DPS meters AGAIN.  *eyetwitch*  I finally had taken enough bullshit.  I told him in no uncertain terms that he had no skill because his awareness SUCKED and he had no concern for his fellow group-mates.  Also told him to suck my cock, and after waiting a few moments for a retort, said "fuck you, buddy" and dropped group.

I have seen this several times, and it ruffles my feathers worse than not using crowd control in situations that could benefit greatly from it.  I get so angry because people seem to think that skill is only measured by the DPS meters.  I don't care if you are the #1 mage on your server and are sporting heroic mode Firelands gear, if you are a dick and want everyone to kiss your ass just because you are doing insane DPS, that's not going to work for me.  Go group with other assholes and you all can suck each others' e-peens.  I would rather group with fellow people who are more concerned about going through situations as a group rather than basking in the convoluted glory of one jackass.
