Galio is the only champion with TWO forms of AOE hard CC
For a champion with abilities this powerful, the rest of his kit is far too overloaded. He has
Q on his E, giving him unconditional mobility making his CC easier to land, and also comes with ANOTHER knockup on it. Why is that even there? Then also his semi global ult, which appears to knockup people for 3 seconds that for some reason also shields his teammates.
Stop making overloaded kits.

Two knockups(Both AOE)
Knockup and knockback(both AOE)
Two knockups(both AOE)
(for all intent and purpose of his ultimate)

QWE skills are fairly useless on their own.
