What if every 5 tier your dragons evolved into an older and scarier dragon. I'm talking about the dragon models, although that would probably require a lot of resources to code, just think about it.π
This is something we definitely want to add! We just don't have the artist time available right now! Hopefully in the future!
I like the idea of a visual representation to progress. Or earn skins as rewards. And different powers to go with the skins ooooooo!
