As with everything else in the Warlords of Draenor there are race changes coming. Warlords is removing Hit and Expertise so any racials dealing with those stats are being removed or replaced. Similar things will be happening to various class abilities.
These are the changes as of 4/24/14 and it’s at least 6 months until WoD is released, so changes are quite possible, even likely. All of these changes will have to be poked and prodded in the alpha and beta testing. One might guess that racial changes might be more set in stone than ability and class changes, but we’ll see.
So here they are, as they stand now. The actual changes are marked in bold. The rest of the racials are added just to be able to see the whole picture. Abilities not linked are not (yet) in WoWhead‘s database.
