...really? Exaggerate much? It's an achievement. This is what's wrong with gamers these days. Some random dude in an internet game gets a little blurb of text attached to his account/character and people scream bloody murder saying it's "elitist"... LOL
And just because some random asshat online might act like a dick and brag about his achievement (like in the example you've shown) it doesn't mean it's Blizzard's fault. By your logic, if I insult someone with the in-game chat, Blizzard should remove all form of text communication from the game, because surely they're "supporting" that form of behavior? Give me a break.
