Many of the toons have been nerfed, but for some unknown reason, Ray remains forever superman. Eternal, because in spite of its relatively short life and protection, surrounded by respective chars, it can survive for a long time that, given its fatal blows, isn't desirable lol very easy to become invulnerable if you are behind someone broad back.
I admit that the game can be different superman, it animates the game. But why Ray? With its 80 shards. Moreover, even superman should not be a problem which absolutely kill your choice. So all the top team are practically identical.
