Should I sell my five stars?

Marvel Puzzle Quest MPQ Tips and Guides Roster and Level Help
1

Before I started the shift to a 3* roster (and before I discovered these forums) I was really focused on getting 5* characters on my roster. I currently have a 2-cover Goblin, 2-cover SS and 1-cover Phoenix. I have 6 champed 3s and no 4s over 6 covers. Are my 5*s killing me for scaling? Should I sell them off? I could definitely use the 40k ISO, but I don’t want to do it if it will screw me down the line.

Here’s my roster for reference: https://mpq.gamependium.com/rosters/PopeBelligerent/

Any suggestions?

Keep them. If you have several champed 3 stars, you should be fine.

Keep them but don’t level them any more.
