Rank-up Advice for Act 5.3 and beyond

Reposting this, could I plz get some advice on which of these champs would help me in the future run?
Currently I'm using only Starky, Quake and maxed 4*s so I don't use them much.

As for OP, Cap Marvel and Havok are great. So are Colossus and Thing. Definitely rank all 4 up. DarkHawk is very good as well, but needs sig.
