A level 85 character creation template has been added so no more pre-made copying though some players are having problems using it.
Using one of the portals from Pandaria to SW/Org now places you at a new panda spot near the Earthshrines.
Pet Battle interface has been added and you can train for it (outside the Blacksmith shop in Goldshire for Alliance, somewhere in Razor Hill for Horde) but it doesn't look like you can actually battle or tame new pets yet.
Disenchanting the new items now gives the MoP mats instead of Cata mats. The enchanting book is very buggy but it looks like they might be adding a filter for enchants by expansion in the future in addition to the current filters by slot and type. I can make some of the new enchants - trying to find and select one I want to make is difficult.
No new tailoring patterns yet.
Finally got The Jade Witch completed but it took some patience before she appeared. Think the phasing is still a little bugged.
