I think we can all agree that min maxing is kind of broken in this game. Maybe it’s viewed as a legitimate strategy, but it really makes PVP less fun for those of us who try to have balanced teams (which we need to have if we want to experiment with different setups, which is IMO the most fun part of the game).
Would it be possible to put limits on star upgrades unless players have upgraded their character to a certain metal/level? We already have this for skins (I know the legendary skins at least can’t be equipped until level 40). Maybe we should have it so that you can’t upgrade a player past 5 stars unless you’re level 40+, 6 stars at 50, 7 stars at 60, 8 stars and above are open at 70. And you can’t go past 5 stars until you’re gold, can’t go past 7 stars unless you’re plat. For characters that start with extra stars (e.g. a Brogan), that’s fine, but you just can’t upgrade them past the level they come at.
For people who already have their characters at min maxing perfection, they get the cash and frags back, and their players get demoted to the level they would be at. They can decide whether to upgrade back or not, but they’ll have to un min max their guys.
