Suggestion: Add a crowd control cleanse to the Sion passive activation skill.

I have been playing a bit of Sion recently whenever I get the opportunity of using his passive, it always makes me feel bad. :( Laning vs a Nasus and dying in a fight just to have him get away at sub 100 HP because he threw a wither on me, while the speed boost from Sion passive skill isn't enough feels bad. I suggest adding a CC cleanse when activating the skill, much like Gangplank oranges. This allows the skilled timing of cleansing the CC without making it Sion seems unstoppable, as you can still throw another CC right after.
