It would be good if Righteous Gust duration be decreased by a second, making it last 3 seconds, and reduce its cooldown by 1 second as well.
It's not so useful to have it last 4 seconds in the map when you only use it to engage or disengage, it doesn't work both ways, so IMO it would be beneficial to be able to cast it a bit more frequently to re-position it, but make it last shorter to compensate.
Galio is pending a rework, or at least a form of update. A few changes here or there isn't going to help him.
What Riot has mentioned is:
When this is happening is unknown. Hopefully it won't take forever.
I like Galio the way he is except for his passive. I'm sure it would be OP to reverse it (50% of AP = MR) but that's the only issue. If MR is in a bad place (and it is) then he suffers.
His W seems best when focused by minions. Maybe I haven't checked the math but if three minions focus me I'm back to full health, for champs it seems to do nothing. His W is really a great ability for Melee Supports because enemies have to make a hard choice. His Q is beastly if you go the AP route. His E should have a much longer CD and a much longer uptime on the map.
