Threads like this really show the biggest problem with the WoW community. It's not the newb or lazy players. It's the self-important egotistical jerks who get butthurt when someone unworthy wins loot and feels the need to play master looter.
The funny thing is that when asked most of these people admit they wouldn't act like such douches in LFD and roll need on stuff they didn't need. It's only LFR that they feel the need to act like dicks complete with all the rationalizations and justifications for why they're actually helping the game by keeping loot away from baddies.
I always knew there were a bunch of douchebags in the game, but it's only from these MMO-Champ threads that I've realized how prevalent asshole behavior has become. And ironically this asshole behavior comes from a lot of people who complain about how bad the WoW community is these days.
