Here's a slight bend, on the whole gearscore mentality.
Heroic HOL--Had a GS 240-rated pally tank, me in Arms spec=225, tree healer=223, and two DPS, both at barely 200ish, obviously barely on the edge of Heroic-ableness.
The tank starts off by saying something like, "Try to keep up, everyone." Then, he proceeds to rock on, at a very good clip. So fast, actually, that no one has time to even pick up the small loot, from the mobs, before he's off to the next pull. I'm keeping up with him, but the healer starts having mana problems, since the other dps are so hurried, they're simply spamming their aoes, drawing the mobs that the tank just leaves behind, in his personal quest to beat some stopwatch in his head.
Well, we get to the place where tank draws all the fire mobs to the far steps, and we all follow behind. The healer follows just a tad too closely, and aggros three of the mobs, at the halfway point. I immediately start whacking on them, to draw them off, and drag them to the tank. I pop all my trinkets, and go into overdrive, because the tank does nothing to taunt. At the end, when all the mobs are exploding, only the tank and I are left standing. I'm typing something like, "Wtf, taunt or something, will you?" But, he's all, "Plate-wearers, ftw! Gimme a high-five!"
I am astonished, as one of the dps simply quits, the healer is running back, with the other dps, and the tank starts pulling the next group! I'm at less than 5% health, by the time the healer gets there, and he's had to stealth past the previous mobs that weren't cleared. Anyway, he saves us, and I'm typing, "Thank you, for the heals."
The healer, who is very pissed, now, tells the tank to slow down, and do it right. Tank pays no heed, at all.
Well, you'all get the picture. After another wipe, in the long hallway with all the iron dwarves, and giant pats, where the tank just decides to go right down the middle, aggroing three groups at once...(god, I hate those little dwarves, who whirlwind!)
Yeah, I'm still wondering why I stuck with it, myself...
I don't care what this guy's gear level was...he was either drunk, a terrible tank, or just being an ass...maybe all three.
On the same day, I did HOL, in regular mode, with a group that was level 79, and just 80, with a tank who'd never been in there, and said so, at the start. He even asked me if I'd spec in my tank gear, instead of him. I told him I didn't pug, as a tank, but I'd do what I could to help him through the strats of the place, and asked the group if they'd let us do it slowly, for once. They were all good with it, thank God.
We got through the instance, with only one wipe (hunter pet aggro), but it was a very fun, and gratifying run, because I got to help a new tank, and "be the hero", at the same time.
I get the "speed run" thing, I really do...it's a rush, but only if it's done well, and with respect to all the members of the group. This is part of the "situational awareness" that is the most important skill a tank can have, whether playing in uber gear, or not.
