Suggestion on leveling up between R4's & R2's.
I have DUST at ascended + R4 with Sig 80.
Got a 7* DUST and she's now at R1 (Unduped).
Should i R5 my 6* or R2 my unduped 7* ?
Similar doubts on my few champs as they available in both versions.
Does it stop ranking to R5, if we have a 7* version already???
Does a 7* R2 is stronger attack than 6* maxed out?
