More to Pykes w?

is a fun champion to play but, I think Pyke deserves more to his w. His w is called "Ghostwater dive" and what it does is it makes Pyke camouflage and he also gains quite a bit of decaying movement speed. That's all! First off its a camouflage not even invisibility. passive is when she hits lvl 6 she becomes camouflaged and champions near her don't have a marker on them whenever shes near but Pyke does? Pyke's W is a whole ability not a passive and yet its a camouflage. There should be at least a passive to his W, Riot made Pyke a awesome champion but I just think that his W needs more to it other than being camouflaged and decaying movement speed.
