Rank up advise - Magik or Dormammu
So I'll just give a brief explanation of the situation here.
I have a 4* unduped Magik and a 4* unduped Dormammu. I want to rank one of them up, and their main purpose would be to serve in AW offense. I want a champion that is able to power control well, but coincidentally, both of these champions are able to power control decently, though Dormammu seems to have a higher damage output due to his abilities, along with the fact he is immune to bleed and poison. On top of that, I already have a 5* R4 Sig 85 Magik, but she is solely assigned to be my BG's War boss for defense.
I only have 3 T4 mystic catalysts, so I can only rank one of them up for now. Who should I rank for AW offense?
