It is not the wiping that bother me, its the yelling a screaming that turns me off. Being that I have done more than my share of raiding, wiping is pretty much a given especially on new content no matter whom is raiding in it. If you are bitching after 4 or 5 wipes in the LFR (lack of mechanic or not), then you must not be much of a raider in the first place. You also have no business being in the LFR, if you are high level normal or heroic raider as that environment was never intended for you in the first place.
