Headhunter Caitlyn
So headhunter caitlyn has some auto attack bugs with the skin. Sometimes the particle drops in visual, and sometimes the application of dmg is delayed or accelerated or disappears. It makes cs'ing hell and also creates other obvious problems when orbwalking/teamfight etc. Maybe no one has reported this, I don't know how popular the skin is, but it seems to be known by the community. I don't have a video to go with this, but it is an easily reproducible situation.
