Lets all run with ungemmed and unenchanted gear in LFR, then after failing 6 times cry for nerf at Blizzard.
People need to respect other people in raid even if that is LFR. If your gear is not gemmed or enchanted then most likely you are not helping your group.
Thats why i see rogues and mages doing 36 dps in 520 ilvl, thats why i see people dying of not enough healing, thats why i see tanks getting 1 shoted.
Underperforming is like being afk if you dont contribute to the fight.
To me It is exactly the same as afk'ing in bg's. People need to learn carrying their own weight. If you can't either educate yourself (via the tons of webpages concerning WoW) or stop playing the game.
Im not saying that in LFR everyone should be OMG so PRO player Paragon material but dont be that bad that even afk seems a better option.
