At this time, I would not be against going back to the old system where there was no random queuing crap, and you had to organise groups yourself. Basically what it was pre-Cata (or pre-4.3).
LFR sucked sure, but now that I've outgeared it until WoD, I resort to Flex. Sadly it is just as bad, what with the random PUGs. I see now why I must get into a guild that actually does raiding, rather than saying they do. No such luck so far, finding such a guild. As a Hunter I know what to do and what not to do, unlike some. I don't go attacking Nazgrim during Defensive Stance, and I know what order to down the Protectors in. Just saying!
Had to vent, sorry. But yeah, it is frustrating when you get so close to ending a boss, only to fail-wipe because some coward leaves without saying why, or someone causes a wipe because they disobeyed the strategy.
