Proposed Sion buff?

This inst anything that would tip over the edge but, when sion is using his ult i would like to be able to interact with it more with activated items or spells like or because sion ult is hard enough to land as it is with most champions having some sort dodging mechanic like a tumble, dash or blink and with ult being very similar but, able to navigate any obstacles with a team speed boost follow up, and arguably a better form of cc from the ult(or at least more reliable form) it just seems a bit unfair to sion.
