Next 4* to champ

I have ~270K of ISO sitting in the bank, and a number of options on what to do with it. I have 5 fully covered, non champed 4*. I have 4 more with 11/12 covers parked at L141.

Fully Covered:

My priority is Peggy, Rhulk, Nova, Moon Knight, Jean Grey, Quake, of characters that I would like to champ. But I am also a bit remiss to let go of covers that can be used for further champing. So my question is:

Do I sell the Carnage and save for a fully covered Jean (or an up and comer) or champ Carnage and take the rewards?

(also, how is War Machine? This is the first time I’ve ever gotten a fully covered 4* that is still at L70, since his Crash hasn’t come around yet).

Sell those covers and champ Jean. You will get so much more benefit from having her at 270 over Carnage.

Yes, absolutely agree to champ Jean.

Thanks for the advice all.

My main argument against Jean was I hate wasting covers / champ levels. RNG has solved my problem, as a token_heroic.png
today gave me my 14th JG cover. Now I have to decide which cover to waste, and if that’s the case, no question. Champing JG.
