Some thoughts on Nocturne

I really like Nocturne's design, at least in terms of appearance and theme. I also don't think he's in the worst spot ever, so to speak. I did, however, have a thought. What if his Q (arguably his most iconic ability, aside from his ult), allowed him to move through walls? This would fit very thematically, I feel, and would really give him some unique (ish. Kinda similar to talon) play patterns.
