Should R4 or wait for better 5*?

I R4 Guillotine 2099 and Human Torch but I don’t know who I should take up to R4 next or if l should just wait for a better 5* champion.

This is my current team.

Any and all advice would be great.

Domino to R4, even though you have Sunspot.

Both of your R4s and Domino are R5 worthy. Sunspot also for R2. Work on those.

Focus on getting that g99 maxed out
