If you try doing the incursion in Vol’dun and you have not done the foothold quest you will be phased from everyone else if you are by the foothold area.
Faction changed one of my max toons and have yet to do the foothold quest for Vol’dun and I get phased from everyone else. Really annoying while trying to do some rare elite incursion quests or Trying to do call to arms/against overwhelming odds and you dont get phased into their server, but are stuck in your own phase.
Happened later with someone else and they were super confused and I asked him if he has done the voldun foothold quest and he said no. So I figured out there is a phasing bug.
Can you please fix that blizzard? I picked zandalar as my first assualt, but havent done the quests for it yet so I’m forced to do those before i can pick voldun.
