LFR is simply not worth it. If I want to spend hours attempting to down a boss, I would rather have it be for progression, and for loot that would actually help me in progression. LFR is insanely easy, and yet you have imbeciles galore who wipe you do to hold-your-hand easy mechanics. I'd rather wipe 20 times on a boss that's challenging in a group of competent people that aren't idiots than wipe 3 times on a completely dumb downed boss with a group of morons who are wiping because they are attacking the boss at the wrong time, standing in bad, or failing to kite the boss around the room the correct way.
Just keep in mind that many of us aren't like you (geared raider).
If you have the time and patience, raiding (organized scheduled raiding) is the way to go.
With oQueue, it's actually faster to do flex than lfr (unless you're a healer, in which case its about the same time). I've looked for raids with oQueue at all hours, and there's never been fewer then 10 flex raids ready to go and looking for people. All you do is hit wait list on whichever group you want to go in, wait to be accepted, and you're off. Anytime, for any length of time; no one cares if you leave early, they can just go back into the queue. Contrast that with the hour wait a dps has.
Admittedly, if you're extremely undergeared you're going to be waiting longer but you're ilvl (526) will get you into 90 percent of groups, and as long as you look for the ones that require 515 or higher (right next to the group name), progression is near guaranteed. Worst flex group I had still got through half the wing.
As far as lfr, well that's what people get for setting no standards. Everytime someone posts about low dps or terrible play in lfr, everyone cries elitist and "it's just lfr". What did people think was going to happen? You've made your bed, now lie in it.
