Actually, I love the idea of new fur, gem and eye colours. For example I would love to see dark blue eye and/or gem colours. And the more colourful fur colour sound amazing! (Maybe we could even make a rainbow out of our nichelings! :3 ) Oh and also, having new markings like you said moon/sun on the forehead would be amazing!! I love that idea! And having bending powers would be nice I think it would take too long to make it, or if they make it maybe it could be another mode, also with the rival tribe, so that people who just want to enjoy the game kinda like how it is now they can, or if you want to play with magic and other tribes you can, but I still think it would take too much time to make those happen... Sorry.
