What you said about team is rather flawed. It's not because they are from the same game that we will know all their possibility. Even if they were from diff. game we would know them too. The basic idea was to make it simpler to balance team. Anyway, it seem teams at all are a 2 big step. I can understand that since balancing would still be very hard at this point. Maybe in a few Zel Melee it will happen. But not any soon.
