Killing maximum level mobs, gets a lot more gold (including vendor trash) than the maximum level mobs in WotLK.
That might be part of the "pile of gold" for leveling to 85th.

The AH is still heavily inflated, on my server.
Not as bad as the opening little bit.
But still, it must suck for those who came in without much savings, and see the entry level epics selling for 75k, when Titansteel went for 10k in WotLK.
