I hadn't noticed any mention of this in the other MoP threads so I thought I'd throw it into the panda blender.
I was wondering while levelling my priest with his heirloom shoulders and chest (for the extra XP) who would get them next. Then it struck me that since new pandas are not Alliance or Horde for 10 levels (almost an hour ) they can't get post from someone who is not on their faction.
Unless there is a relaxation of the Azerothian Postal Service they will have to cope without heirlooms!
Is this the real reason for all the Panda hate?
