Who to R4 to complete Act 7?

Gunnes

Looking at my 3rd R4 and yet to finish act 7 (currently at 7.1.4). I'm thinking CAIW for class diversity but CGR has quite the damage output. I may have some other good champs but don't want to invest resources (gold) in them or I don't play them as well as others (Tigra / Shang Chi) but simply haven't practiced with them much either.

Some options:
CAIW (Cap IW, captain america infinity war)
CGR (cosmic ghost rider)
Dragonman
Shang Chi
Warlock
Korg
Tigra
Hulk Rag (ragnorok)

Existing champs:
Hercules R4
Dr Doom (DD) R4
Sauron 7*
Guilly 2099 (G2099 Guillotine 2099) 7*

I also have 3 generic 6* AGs and a Mystic 6* AG.

Shang Chi

I think Shang Chi is a good option since he is already awakened and you already have the best cosmic in-game (Herc) so you don't really need CGR for act 7. Besides Shang Chi can be very useful for Bahamet and act 8 in general. Hope this advice helps !

Ultron is a great option against the final Kang boss. Could consider ranking him up.

You can't finish act 7, yet alone 7.1, and you have herc and doom???

Not can't lols. Just haven't gotten around to it with time and doing the recent events (which focused more on BG, AQs, etc). But also yes not the best with advanced story quests. And yes I have Herc, doom and 2 seven star champs and more. Oh you mean Herc and doom should be enough to complete A.7 yes, lols.
