Even worse is when these types of folks hop on their alts.

While leveling my priest recently, our warrior tank (no BoA gear) wasn't exactly doing the best tanking job in Wailing Caverns. Instead of guiding him as to how he might be better, some elitist 7th-time-through-the-game prick just kept saying things like "u suk" [sic] and "ur a ****ty tank" [sic]. Like I said...he wasn't the best tank in the world, but it was freakin' Wailing Caverns and it's not like anybody died.

I did what I would recommend everyone do: I berated the elitist for being such a jerk to someone who is obviously learning how to tank. He didn't get it, of course. Instead he tried to defend his behavior by saying idiotic things like, "lol u can learn to tank by watching youtube lol," [sic] and eventually dropping group.

Related plea to elitist pricks everywhere: STOP PURPOSELY GIVING WRONG ANSWERS TO NOOB QUESTIONS IN TRADE CHAT! You people purposely make the game confusing for new people, then wonder why they still suck when they enter their first heroic. Figure it out, stupid.
