Which of these champs should be my first Rank 5 Five Star?

Cunnus

Just about to have all the resources to rank 5 one of my 5* champs, I'd consider saving to use on my 6*s but my 6* roster isn't great (Storm and Cable)

Save for someone else or wait for a dupe

Personally if you HAD to choose I’d be tempted to say Sparky. However the dupe really pushes him from great to amazing

But as is he’s better left at r4 for the moment

Ghost Rider, Unduped

I'm a fan of GR here because he's a healer, buff removed, AND power controller. Stark Spidey is amazing, but I usually suggest going with a healer first to aid in longer quests and difficult content. Of course, GR is also bleed immune, which helps a lot!

Stark Spidey, in my opinion, can do very high damage just fine at R4...so fine to wait on him a bit. However, I do think he could be a quick second on that. His dupe is only great if you put him on defense in AW...doesn't matter as much if you use him on offense or in AQ/questing. In other words, no reason to wait on dupe to R5. Even without dupe, would be extremely helpful in the most difficult content such as LOL.

Don't r5 an unduped 5*. simple

He was my fist R5, couldn’t have been happier, he’s a beast.
