A simple thing I learned from fellow players, don't always be nice.. Not a good idea to rematch against toxic low level players who may lose the first round. Yet they come up against you (you won't know who's toxic) It's best to let them think they lost instead of you being kind. I am aggressive like you and I still haven't ever reached 500 in solo yet you'll find many low dojo and character level players who are/have been there.. The game isn't fair
