Cavalier planning

Joniemaximus

I'm in the planning stage of making a run at completing 6.1. I know that i'm probably not in the best place champs wise currently so wondering where i should focus my resources. I have the resources almost to take Magik to R5 but wondering if i should use those resources elsewhere.

My Roster is:

6* - Loki, Venow, Drax, Captain Marvel - i dont think any of these will be particularly helpful.

5* R5 - ArchAngel

5* R4 -, Magik*, Starky, Rulk, MagnetoRed

5* R3 - DrDoom, Ghostrider*, Apoc, Hawkeye, Dormammu , Nimrod

5* - Hela*, Falcon, Karnak, Nightcrawler, Colossus, Starlord, Black Panther OG, IronmanIW, OML, Bishop, ThorRag, YellowJacket, DocOc, HulkRag, Overseer, WinterSoldier*, CyclopseBlue, SPidermanOG, IronmanOG, CapatinMarvelOG, Antman, SpiderGwen, ThorJF, SUuperIronman, Ms.Marvel, Groot

I'm thinking it might be worth ranking Nimrod, Ghostrider, Dormmamu to R4, and ranking Overseer and Hulk Ragnarok to R3 but not sure they're the champs best utilise resources.

Doom! the guy is a beast, even unduped! My 5*r4 unduped is clearing lots of content in my 2nd account
Dormammu is a waste, I have a duped r5 on main account, I never use him (he was my 1st 5*)
IronmanIW was my 1st r5 and still is on my main team
I don't have a red Magneto, but if I did... he would be r5
Colossus is great - wish I had him
Nimrod - just got him to r5 (unduped) but he's a great option too...
