As with previous events, we will provide an up-to-date list of BattleTags shared by members of the community who are looking for someone to experience this event with. Please provide both your BattleTag and your region when posting. It will make it much easier for everyone to connect and figure out who to play with. Let us know when you've completed the event and gotten your Cho'gall, we'll take you off the BTag list so you don't get super-spammed by friend requests when you no longer need it.
