Good news is the black market auction house has this now on sale, current bid is only 178k ! Compared this to the 250k firehawk mounts that guilds were selling, it's still dirt cheap !
By comparision, mimiron's head on other realms BMAH went for :
Proudmoore : 999k
Draenor : 699k
Good luck all ! may the richest alliance / horde wins when auction ends in 12 hours.
