I'm sitting on a surplus of 40k honor at nearly rank 11 after buying every piece of PvP gear. Once I hit rank 12 and buy my weapon, there will be no reason for me to PvP with this character until the epic armor set is added. I don't want to spend months getting dominated by raiders in T2 while I'm honor and rank-capped and still in blues. I'll be leveling alts instead.
I think a good compromise would be to release the epic PvP set a month after the next patch. That will give raiders a month to enjoy the new raid, but it won't allow them to ruin BGs for PvP-focused players for months.
