Galio E change

Galio right now is a strong counter pick for a select few champions, mainly dot champions like malzahar and cassieopia, but outside of the laning phase he doesn't contribute much. This likely has to do with his lack of an initiation tool and an ultimate that requires initiation, restricting it's use to the flash cooldown.

I propose the following changes to his E to make him a competitive choice:

E: Charges up to 3 seconds, with a short delay of .25 seconds before release. Maxes at 2 seconds and refunds half mana and cooldown if it reaches 3 without use.

Charge range is initially 600 and builds to 900 with a speed of 800 to 1200. Enemies struck at the impact point (adjusted for his size) will be knocked up for .5 seconds while enemies around him (325?) will be slowed by 20-30% and suffer damage. Possibly more damage at impact point. The charge animation should be pretty obvious (he flies high up into the air) and he is stationary (or moves slower) while charging. As long as he charges for at least 1 second he ignores (terrain?) and unit collision.

Alternatively he could simply charge in a straight line connecting with the first struck champion and leave that speed buff in his wake.

Would that ability make galio usable in competitive play?
