Kindred W has weird lock on feature.

Hello, I decided to try playing Kindred since they went on free champ rotation and I've noticed that when you select the W spell to cast it, for some reason it highlights Lamb in yellow. I don't know why it does this or if I am missing some hidden benefit of casting the spell on Lamb directly. Or if it's just something left over from before. After asking around ppl have told me they were reworked.

Anyways, it's pesky and minimally interferes with my game play so I thought I'd make a post about it. Maybe someone on the team will fix it and I won't have to deal with the mysterious W lock on thing.
