To me, Corvus is overrated. But it depends on the content also, Corvus isn’t that much helpful in act 7 unless boosted and duped, but I don’t see him so great. Hit monkey is amazing and has helped a lot with act 7, but Shang chi is just the full package, the problem with hit monkey is his small health, low block prof, and can only purify 1 debuff at a time.
Shang Chi or Mr F given that they're all unduped. Both get a nice benefit being awakened but neither sig is essential to their kit. Mr F has some of the best control over a fight in the game but has a fight by fight ramp up that doesn't suit everyone. To really maximize his abilities corvus needs to be duped and running suicides, if that were the case he'd probably be number 1 but since it isn't he's behind Shang and Mr F for me. For most people Shang is the pick but if you're good with a slower more controlled fight Reed is among the best.
Comments
Can't comment on Fantastic.
Shang-Chi doesn't need it, neither does HM.
His ability to control a fight, remove debuffs when he wants (or leave them, if he wants, for Willpower) and deal huge damage is truly amazing.
His dupe is nice, but not a necessity.
Beyond that, man's drippin with utility and damage.
You can't go wrong with Mr. Fantastic either, he's a solid champ. Kinda needs the dupe though, but still very solid and loads of usefulness unduped
