I do other stuff in LFR. I just beat Quake again, so I'm playing Scribblenauts on my 3DS.
This is part of the problem, while you can still group with decent players in LFR, they are lazy and just afk.
Other problem is terrible players who just don't learn or listen.
LFR has been frustrating this tier, and I hate it. However, I will still do it each week for VP and gear upgrades, however, my main doesn't need anything anything from it, apart from tier for the bonuses.
Will still do it on my alts.
It should get better as the weeks go on, when people actually learn what to do.
The most frustrating thing is, getting a boss to a very low %, with terrible DPS (30k dps, in 470+ gear is mind boggling bad), then wiping due to healers having no mana because of DPS being terrible.
I don't like LFR and only do it for the gear, which means I don't do MV anymore.
Also annoys me the I have to queue as dps although I'm main spec healer - would be better for the queue and the raid - but I don't need healing trinkets and can only get dps trinkets as a dps, while all other loot is equal for both specs.
Being a healer and having most raids completely derpy where they stand in all the bad stuff i have quite a bit of fun trying to keep everyone up. Oh and those Garalon fights where i break 100k heals ;D
