Should I sell my 5* upper characters?
If I do, would I drop down in leveling so I don't have to face 450+ Gambits every other match? (not at all would be great)
What level is the max I should have a 5* character before it effects my facing nothing but championed 5*s?
Are my Daredevil and Black Panther too high at level 390? Would I have to sell them too, to make sure I don't face mega high Gambit teams, or would it be safe to keep them?
