Senna Ability Thought

So.. in the video for Senna, she stops Thresh's hook with an ability. I have a semi-prediction and semi-hope as to what this is.

I would assume this is some kind of skill block that is usable on a teammate. Knowing Riot, it might be invincibility as well, but I hope it is neither of this.

Instead, I really hope this is a dual-use ability like Lulu has. Specifically, it would do this:

If cast on an Ally: Block any displacement effects on the target for [X time]. And maybe grant some kind of buff, etc. If cast on an enemy: Ground the target for [X time]. Alternatively to this, it could prevent skills from allowing them to displace themselves but not items or flash.

I think this would be extremely beneficial in a game way too full of mobility as it is and thematically, it would fit the character very well as it would stop people from taking Thresh's lantern for example.

Just a thought Riot, just a thought. :D
