Multiteam Game Mode
Would be nice to have a multiteam game Mode like the 3v3v3 concept or with four teams : 3v3v3v3. Maybe with 4 teams, that will prevent two teams team up agains one. That will be more strategic, because you always want to attack the one you think will win.
At the end you will have ranking with position. team finish first got more IP, team finish second more IP than third position, etc.
The map and structure of the game can be similar of the multiteam in WoW.
