Expiring T4c skill - Any of these skill worth R2 or R4 5*

I don't wanna waste my T5b as I have limited ressources. But i need to rankup someone as i have 6 expiring t4c skills in 2 hours.
As i don't rankup 5* any more, I am confused about the rankup.
Please advise (still have Act 7 completion and Act 6 ecploration to do).
Thanks

If you don't want to waste the t5bs (understandable), keep in mind that you can trade those t4ccs in for other t4cc. It's not a 1-for-1 but it's better than letting them go to waste or using your hard-earned t5b on champions you are not sure about.
