Unsure if it's similar enough to feel miffed.

A million years ago I came up with a highly detailed concept for a shadow reaper character, yes I even called him that, with a living demonic scythe, and now kayn. Granted my design is less void demon and more heavy metal, and the ability design is much simpler as the game was simpler back then, but in general you know...

Also yes that's me, some point in the years I wasn't playing my account had been hacked and I didn't get it back before the summoner name change had already irrevocably affected all my forum posts.

Even if they really got no inspiration whatsoever from it, it would be cool to see a skin based on this old concept.
