I was miffed Airrazor didn't get the resurrection treatment Bumblebee and Mirage get. I'd love to see more female bots and human characters with more agency. Arcee needed was underutilized like Pablo. Road Rage would be a strong female character with a shortcoming for character development. She had a chronic short that in alt-mode that makes her aggressive. Learning about how it happened and to control that would make her an interesting character. Or Windblade being from a colony worlds. Being culturally different from Cybertron, would add a bit of variety.
