What if Rune Prison was Ryze's ultimate instead of Realm Warp?

Make it the same size as Realm Warp.

Those affected by Spell Flux are rooted. Without Spell Flux champs are free to move, but are cage, like a prison.

The duration of the root is at max 1 second but the cage itself is like 2 or 3 seconds.

I'm just wondering if it would be worth considering since it's such an icon ability of his and yet his most problematic one. Plus, the way Riot depicts Rune Prison from RISE makes it such a commanding ability for Ryze.

Then have his Realm Warp be his W. Still have it as short as rank 1 throughout all 5 levels, have it be some 80 second cooldown. Like Quinn's and Ashe's W. But it can be reduced by proc'ing Spell Flux. Since Realm Warp seems to be deadlocked into his kit since he had his own trailer in Ryze: Call of Power. As it seems to be his regular method of getting around places so it should be something he can regularly use.

As far as the E > Q > E > W > E > Q spam or w/e it is now since he has undergone so much ability reconstruction, I'm at a loss for.

PLUS there's always a good chance he's going to get reworked. Again.

It was always a passing thought that I wanted to get out there.
