Lately, I always think about this, why do Heroes' appearances not change after they evolve.
When Heroes evolve, only the star under their feet changes (I'm not mentioning Heroes' status), and I think it's boring.
It will be better if you can add Heroes' developing appearance. For example, one star Hero - the baby, two star Hero - the teenage, three star - the grow up, four star - the middle, and five star - the wise.
My artistic skill is zero, so I use Pixar's sketches of Carl as replacement.
I can't believe this. You did a lot of things that make players disappointed and stayed away the best idea ever. Good job...
