So by your logic, first you have to go through a few weeks of LFR until you've "learned" your class and then, once you've met some imaginary mark set by some random dude off the internet, then you are "qualified" to start to roll on loot.
Gotcha.
I get hating those douchebags that /AFK the fight, or die on purpose, etc and are a nuisance and leeches, I really do.
But guess what? Those are the same douchebags you get in BG's since forever. LFR didn't invent those people.
Oh, and the new LFR loot system that will take place in 2 months, well, that will invalidate these self-appointed loot adjudicators. So, enjoy it while it lasts?
