Heimdall
Heimdall hits like he is in the peewee league. This is really messed up that a featured with so much potential be worse than carnage.
His only saving grace is his synergies.
I write this because if you're like me and r3 your 5 star you regret it and hope that no one else will make the same mistake.
CG, Prox, Medusa, Hype are the main cosmics I'd suggest.
Unless Kabam is going to fix heimdall damage output, he will be a Collected toon, that is never used.
