Rank up decisions: to future-proof yet or no
So here's my dilemma: I'm about to have enough resources to R5 another champion. I currently have 7 5/65 5* and 1 R2 6* (Unduped CapIW). I have some amazing 5* I can take to R5 (Omega, Spark, Ghost, Corvus)and quite a few duped 6* (Void, Luke Cage, Human Torch).
Tell me what you think and why...
