I don't know if you have one, but I sure do. I got this one... I don't remember when. If you have a unique armatar that only YOU have, post it here! Just make a post and share it with everyone!
I think they should just keep it how it is then but add a few more to the selection. I'm a horrible drawer so it's going to be hard for me to make one myself.
I think there should be a drawing option in AG3. So when you went to armatars, there would be a 100x100 square that you could draw in. Then that would become your armatar.
