To any rioter who has the time

Just wanted your thoughts on a simple ability change for Shen that would make it more fun to use and fit in with his role and theme really well. I feel his W is basically useless. It's kind of that move that you just slap on in fights when the enemy team is focusing you and that's about it. I frequently try and use it in teammates to stop them taking damage but most times they just walk out of it. And if I ult someone and want to help fight someone I have to use my Q to do any damage so I'll probably need to pull my blade with me so I can't really use it on allies and Shens whole deal is saving them. I was thinking what about making it so you have the option to push the spirit blade to an ally with W so it will activate on them. I don't think this would be too overpowered or anything. And I was thinking if that would be cool to have it so if you manage to pull the blade through an enemy by using your W to an ally, they get the the same slow as your Q when heading towards the ally you blocked. Not sure how that but would be in the op or not scale but yeah. That's about it. Lemme know what you think!
