I’m fairly close to taking my second 5* to rank 4 but I’m not sure which one is more worthy of it. I’m currently on my path to uncollected so perhaps Sparky would be better but Warlock usually helps me more in the game overall due to his immunities and power control. I’ve only recently started to play with Namor and BWCV but I know they’re quite good as well, Any tips or suggestions?
(My only R4, currently, is CAIW.)
