Nocturne Visuals

Im just wondering if anyone agrees that Nocturne could use a bit of a visual improvement or if they have information regarding if he is going to get one in the future. The changes I would like are not so much to his model but his tail, when I play him it always clips through himself and if he turns around sometimes it becomes hidden in his body. Along with this I feel like his W could use a bit of an update its visuals looks pretty pathetic in comparison to Sivirs spell shield and the effects for and imo. These are just my opinions and i'm wondering if Riot has mentioned any plans to improve them. Thanks.

EDIT: One of the reasons im asking now rather than in the past is because of the Cassiopea tail changes on the PBE making it more simmilar to ASols and I reckon they could put something like that on nocturne.
