Is GR worth ranking up?
So my current top 5 champs are 5* 2/35 stark spidey, 5* 2/35 kingpin, 4* 4/40 angela, 4* 4/40 civil warrior, and 4* 4/40 Sabertooth (all unduped).
I just got a 4* GR from a crystal, and I know he's a pretty solid champ, should I rank him up? Or is my current top roster solid enough?
I also have a rank 1/10 4* duped Doc Ock, which I've also heard is a pretty solid champ.
Whats my best move here? My next big goal in getting to uncollected (I'm almost at the maestro right now) if that helps, and my alliance doesn't do a ton of wars sadly, so AW isn't a focus for me right now.
