Take 6* Namor (unduped) to R2 or concentrate on improving 5* roster.
I have the opportunity to take my 6* Namor to R2. Should I do it or continue to concentrate solely on making my 5* roster better and improve versatility?
Currently, I only have my 5* Domino at R5, and Medusa, KM, Thing, and IMIW at R4.
