sorry OP, but the BMAH is now a core part of progression: look at blood legion who spent multiple gold caps on 509 items, or vodka who essentially harassed people out of it.

not that it did them any good in the end, but still.

in my opinion, if you cant achieve it by raiding, you shouldnt be able to get it period. some things should be left alone, now you are going to get people who have never raided anything but the auction house, trying to show off their rare mount that they "earned".
