A while ago we wrote about the removal of Leveling Realm First achievements in Warlords of Draenor.
Apparently those are not the only Realm First achievements to be removed in the upcoming expansion. The Professions ones are gone as well. It seems like they wont work well with the WoD professions changes. We do not know what those changes are at the moment, but I’m pretty sure we’ll find out soon.
@jimmyolsenblues Realm First profession achievements are also gone. They don't integrate well w/profession changes.

So, if any of you prepare for these achievements, forget about it and focus on something else.
