MDI is coming back at the end of this month! If you're looking to find other players to form teams, a new #mythic_dungeon_invitational channel has been added to the "NA Alliance Mythic+ Community" discord! If you are just generally excited about MDI and don't plan on competing, still feel free to chat with everyone else about the topic.
Please use your already available discord topic to post a about new channel. Having 2 "same" threads up which both (will get bumped I assume) is bit spammish.
