Hey there! I exclusively play this game with another person, and it would be really great if we could start and/or join team ups (with space) as a group. If I'm in a group with a player, and we both have the dungeon unlocked, we should be able to click 'team up' and both of us are automatically entered. If the other player doesn't want to join, they can just click the team up bubble and click 'leave' if they don't want to be in the team up.
Team up is my favorite part of Wizard101; it's so fun and easy to find fights all along the spiral since I love doing PVE fights. But me and my buddy love to do team ups together, and the current system makes it harder for us to work as, well, a team.
