I was thinking how entertaining it is to attack chameleon defense teams and see my heroes operate in new colors.
Why not freshen up things and randomize the colors for all season 1 heroes (not costumed) such that there might be a purple Lianna, yellow Azlar or green Vivica.
I think the core community in this game has moved past the point where collecting the season 1 heroes is still a part of the experience. Different colors could help revive interest in some of the heroes at least.
I would point out that the costumes are very cool and sg could both roll out more costumes and randomize colors. It doesn’t need to be a ‘costumes already exist’ kind of thing.
