It would be nice if the My Team tab would update when a person joins and you are already on the tab. The only way to see the person is to exit out to the Team Zeppelin and then select My Team again.
This would really help alot when the team is open and you have reduced your minimum mp requirement and are being barraged with people joining.
Another way to solve this problem would be to change the minimum mp from a drop to an integer field that you can input a value for.
I dropped my team's mp minimum from 1500 to 0, because I really wanted to drop it to 1000, but can't. So I dropped it 0, but then had to kick the numerous people below 1000 that joined.
