I did the LFR yesterday on a rogue alt I just hit 85 with. She's pretty much all 371 pvp gear with random boe 378s I bought her and the 397 daggers. Anyway; while I didn't do amazing, I didn't do bad either. I was holding just over 20k on bosses.

Long story short. This was pure pug. Our highest dps was 24k and I was steadily 3rd. So that tells you the damage requirement (seemingly easy). To clear the four bosses (LFR pure pug mind you) took us 46 minutes. That's faster than doing the 5mans has ever taken me pugging. It's definitely worth a look at those 'complaining' about not being able to get tier from valor points. It's more or less a 5 man level instance super zergable

Edit: And as a solo queued dps it took me 2 minutes to get into a group. Not the standard 30-45 I've been hitting
