Aatrox W granting true sight

The title says it all. Aatrox has had this bug since release and for some reason, it's not being dealt with. Now, I'm fine with this happening since it is a tether and it makes sense, but I wish it said it on the ability description. I was really pissed when I was looking it up and it wasn't even in the ability description. So not much of a bug but an update to the ability description.
