Selling honor gear wont even net you enough to cover your repairs, honor vendors are still only selling Cataclysm stuff and would encourage more botting than gold for rated PvP.
And that is why it should only be for RATED PvP like Arena and RBG, not for unrated battlegrounds. Have fun botting arenas.If blizzard buffs gold gain even slightly in pvp, the bots will be unbearable and blizzard will have to do something about it ($) and that just is not in their budget.
