Devs,
I don’t know why the paid tournament ticket exchange npc was removed from Heart of the Mists. I cannot find any announcement that this was happening and while there has been ample time for most to exchange their tickets, some may or may not have had that opportunity, leaving a stack of now-worthless tickets in the pvp locker.
Please consider bringing this npc back for a time and making an announcement that it will be removed by a specific date.
