Just had a shocking experience in a random heroic...
Got put in Heroic DTK with a tank that had a gearscore of 2364. A death knight with just over 20k health. We had a tree healer with a gearscore of around 4500. Without getting into a debate of skill > gear or gear = skill or whatever combination of those 2 words and comparison operators you prefer, with a gs like that, the tank could not possibly have been anywhere near the defense "cap."
Not to mention I'm a 5.2k gs warlock that generally just spams Seed of Corruption unless on a boss through heroics, and I've pulled aggro plenty of times doing that.
Not with this tank.
Although his health got pretty low a couple of times, the healer never let him die. In fact, no one died, because no one pulled aggro. Not once. And with all the dps having over 4.8k gs, that's pretty impressive. Grats to you, Mr. Tank from the Earthen Ring realm.
Anyone else got any pleasantly shocking stories?
