[GAMEPLAY] Sion ult should ignore CC (but it doesn't)
While charging, Sion should be immune to all CC according to the tool tip:

Messing around in an ARAM today, we found that when a Sion and a Hecarim ult at each other, Hec fears Sion. When Sion and Malph ult at each other, Sion runs through no problem. When Vi ults an ulting Sion, Sion is knocked up.
Seems like the inconsistent behavior (Malph knockup no, Vi knockup yes -- any CC, at odds with the tooltip) is probably a bug.
