It's funny how ppl just say "It's no big deal it's just LFR". I have been in groups that kept wiping because all the healers was cheating their ilvl to get in. I agree that in LFR you can carry ppl easy, but only if the rest of the group is good. I've seen many groups lately be fails.
I'm not sure where all the courtesy for other players/ppl has gone. Doesn't matter what role I was playing, I always made sure I was geared for the content and could pull my weight. Now days I see a fury warrior enter as a tank with a 2h in one hand and a shield in the other. Yea maybe you can tank as fury with your guilds but why put the rest of the group, or the healer through that?
