Character who gained or lost the most in reboot?

[Agent Z]

At this point how can you even argue that Cyborg should be disassembled and thrown into the sun. He is so lost and damaged as a character.

Because no one would make this argument about a character they like no matter how badly they are screwed up by the writing. Anyone who is making this argument about Cyborg likely had issues with him long before the New 52.
