Feels like the sample of playing with the "strict" balance is a bit small, however from what I've experienced clans seem to be getting split up alot more, but it also felt like the balance between classes were greater than usual.
That's how I feel too. It could be because bannerstacking players get split up a lot more, and some may play the same classes. There shouldn't be any code in the strict autobalance or anything that determines peoples classes, but it could be pretty neat to have. I've talked to Professor about this, and if/when he got time, we could maybe create a new teambalance system with classbalance. There's a bigger possibillity that it will happen, now that there's rumours about PTX joining the coding team.
