anyone know the criteria for unlocking these?
So far I know:
1 title for completing survival mode per character.
1 title for your first win in ranked per character.
1 title for your 10th(?) win in ranked per character.
1 title for your 50th win in ranked per character.
1 title for moving up a league in online.
I think you also get titles based on the number of matches you’ve played but I don’t think it’s limited to ranked.
