I think Cassiopeia could really benefit from a remodel.
I was just watching the SKT vs Flash Wolves game when this occurred to me. I know you were very proud of the work that went into Cass' model when you first released her (she was the first champion to get a "making of" video about how you modeled her and her animations) but when I watched Faker playing her against Maple's Aurelion Sol, it occurred to me that her snakelike tail could really benefit from the same technology you used to create Aurelion Sol's long, sinuous, twisting, serpentine body.
I know it'd hardly be a major priority, but it's something you should keep in mind, OK?
