Why? It was an accurate description.
Anyway,
LFR is LFR, it's always been the same, queue up, get in and afk. You'll get those types that try really really hard and turn up with fully buffed, sticking feasts down and wasting flasks, and then you get others that turn up and barely know how to wipe their own ass. When you get such a mix and spread of players it's never going to go smoothly.
As for G'huun, again it's LFR, but just a handful of people ignoring mechanics can cost you. These folks should at least be reading for lethal things to act on so they don't look like complete vegetables, it's really not difficult. LFR exists just to see the content, and whilst it does reward loot it's not as if it is of a high ilvl, it pretty much only exists to give the players who can't raid; for their various reasons, a chance to look at the bosses, fights and mechanics.
That being said, on the day the LFR G'huun wing launched, pretty early on in the day, I shit you not, there was some complete tool in the group I joined full on raging after the first wipe (think we downed it on the 4th attempt once people acted on the debuff and whatnot). Honestly he was full nerd raging, he was either out of Red Bull or he just needs to avoid LFR, or both. His issue? And bear in mind this was literally within an hour of LFR being up, "have none of you retards done this before???". That is a direct quote from what he was saying in raid chat. I guess a couple of people may have done it on normal or heroic, but for the most part it's safe to assume that almost nobody had done the fight before.
Most of the time in LFR it's not the bosses that are the problem, it's people like this raging asshat and people too lazy to just read a couple of lines of text, classic LFR. In short, be prepared for a few wipes in the first few weeks while people dust their brains off.
