I luv this guide sooooooooo much. #tryitout!
This is the best koshan type for me and it fits perfectly on how i play her. Maybe u should of put stealth trap on both side for vison

This could be good in some scenarios, for example if your support is not building support like they are supposed to. I would be concerned with overall a team not having enough damage if there is another support member on the team. I think twirly death does help somewhat. I'm curious enough to try it out and let you know my feedback. Nice write up!
