Which skill champ to rank?
I'm really stuck on which skill to rank up and could use some advice. So the question/choice is do I bring 4* gp to r5 unduped... 5* Hawkeye unduped to rank 3 or 4 * crossbones to r5 duped. I keep hearing the future is 5* and all that, but I find it hard to believe that 4*s will be completely obsolete and no longer useful..anyways would love to hear your thoughts. Thanks for any input
