Logical Change to Galio's Bulwark and Rightious Gust

TL;DR:

-Remove damage from Righteous Gust and make it a trail that Galio leaves behind(AoE buff) -Add passive to Bulwark that grants Auto attacks stacking magic damage for 5 seconds.

Many players would agree Galio's mechanic's contradict themselves, and he should have more reason to be on the front lines initiating fights, dealing damage up close in place of ranged. To accomplish this I have some suggestions for changing Bulwark and Righteous Gust.

I don't know whether it would be classified as a "point blank area of effect", "self targeted buff" or both, but I believe Righteous Gust should increase Galio's movement speed and leave a wind trail behind him for the next 3 seconds or until he's traveled 1180 units(same skillshot range) that increases allied movement speed in the direction Galio traveled.

In addition, Righteous Gust should no longer deal damage.

Instead I think an offensive stacking passive should be added to Bulwark which grants Galio's auto attacks an additional 4/8/12/16/20(+8% AP) Magic damage stacking up to 4 times and lasting 5 seconds.

I'm not sure how much base and scaling damage this offensive passive should have but I think my estimates are a fair representation.

Overall the change to Righteous Gust would make that ability much more useful to Galio and his allies, as well as providing more reliable engages.

And with the Change to Bulwark it would provide a more sustainable source of damage that rewards front line skirmishes

These two changes combined would help define the role Galio Is meant to play.
