I apologize if someone suggested this already.
So in theory, levels will go up infinitely. Seeing level 100+ people is uncommon but not rare. I think what might be a neat idea is to do something like CS GO has done (I know I’m gonna get hater for saying that B) ). Each year there would be a special level trinket you can get once you reach a certain level. It would be like leveling up your service badge in CS Go: once you hit level 40 your grade your service badge (or get the one for the new year if you haven’t already) and go back to level 1 (or 0 I can’t remember what you start at). I think it’d be interesting for them to do this in DB. It might help get rid of these level biases as well as give older players an incentive to keep playing.
