So that's what, less than 10 mogu in 6 hours versus the 6 minutes it took to kill a rare, get the key and run the scenario for 10-15 elders? That's not a very good time/reward ratio you're promoting IMO. It's crazy I'd need to spend 6 hours per character to get 1 coin per boss for last tiers raid.
I'm not trying to make a mountain out of a molehill, it's just way out of whack to me.
While you're also sprouting 496 tokens out of the ass and might get a token to upgrade one to 533. I think I might get all of my alts to SoO LFR ilvl today after I sort out the 24 timeless pieces I looted during that period.
