Yuumi's W does not give as much damage as is says it will or currently is on the spell description!

I don't know how I'm not seeing anything about this when I google it but her w is not working in more than just what the title says.

For example, I can be hovering over some one right next to me if i'm in some one and it will not put me "in" them. It will unattached me instead! Not only that but unless the tip of the cursor is on the champion you want to attach it will not! the area that lets you attach NEEDS to be bigger. Many times i'll w into some one but .00001 cm from them i'll still get blitz or thresh hooked. I get that jinx and veig e will stop you but the whole point of the ability is to be un-targetable and to dodge skill shots since you die instantly from one attack. these are basically qol issues that shouldn't be an issue in 2019 when you release a champion and would increase winrates for sure but the w damage issue needs to be hotfixed.

You can test this yourself btw. When you're not attached press shift and hover the w, it will show you how much adaptive damage it will give some one. Now attach to them and you'll see the issue. It shows that it's giving 10 but only gives 6. It also shows you how much it should be giving them and you when you're attached. Just Look at how much they have, lets say 220 and it says it should be giving 40 but when you detach it says 200 it's only giving 20. I need you all to do this in your games if you play yuumi and comment here and make sure riot sees this sh*t.
