Idea for Skarner and his suppression!

After watching one of Gbay99's videos, I got off to thinking about what really could help him become a stronger and better yet, keep him fair and fun! In his video he brings up a good point about Yasuo's ult being uninterrupted by anything (except for death) and how it's fair because of the required set-up, and I believe Skarner could benefit greatly from something like this.

Imagine for a moment, that anytime Skarner lands his 3 passive strike on someone, his ult paralyzed them for a set time, making his ult inescapable even with QSS or even give Skarner some major buff to during the ult upon a 3 passive ult instead!

Doesn't have to be that, but just a some food for thought! Let me know if anyone else has some feedback on the matter, he's one of my personal favorite design's, so I would love to see something good come his way!
