Galio should be a guardian that will do everything he can to protect his allies at all costs.
I feel like Galio has some interesting abilities, but they don't exactly mesh together. Some parts fit his theme, while other parts sorta just feel a bit like.. filler.
**Passive - ** This is an interesting effect, and few champions have similar abilities (AP and HP on Vlad, Armor on Rammus, might be a few more). It kinda fits him as a tanky mage, but I wouldn't be too upset to see it go.
- If changed, I could almost see Galio's passive getting some aspects similar to his W, though I can't say for sure how that would work.
Q - This is the ability that seems to be completely out of place on Galio. He plays like he should be in close quarters, but his Q (and E) go against that.
That said, while his current Q doesn't really fit his theme, it does technically fill in the gaps of his kit.
- If changed, I could see this becoming an auto-attack adjustment. Empower his next auto-attack(s) with extra damage and a slow.
If it stays as a ranged ability, it will still likely have some form of slow.
**W - ** This ability is one that's quite unique, and I like how it works. Give an ally (or yourself) a boost of Armor and Magic Resistance, then get healed whenever the buffed target is damaged. I just wish it didn't look like a shield, because it really isn't a shield.
- If changed, I could see this and his passive being combined somehow.
I could also see this being changed into an actual shield, though I don't think that's the right way to go.
Adjusting the way it heals might be a wise idea. It could stop healing after X number of hits taken, or it might could heal a percentage of the damage taken.
Perhaps make it self-only. This would help enforce the tanky part of his kit at the cost of the mage/supportive aspect.
**E - ** I like this ability, mainly for the movement speed area it leaves, but thematically, it almost feels like it has the wrong focus. Being a skillshot fits a mage, but I don't exactly see Galio as a Mage.
- If changed, I feel it should keep the movement speed area. Beyond that, I think it should be changed from a Skillshot into a Dash/Leap type of ability. Leaping/Flying into the fray to draw the attention of his enemies, rather than blowing a big gust of wind.
**R - ** The iconic Galio ability, everyone knows this is what Galio can do. It's also a bit unwieldy to use to its maximum effectiveness, similar to Amumu's and Nunu's ults. Get in, ult, and hope you don't get interrupted or killed.
- If changed, I wouldn't know what to do with it. It's probably going to be adjusted in some way, but hopefully, it will still work fairly similarly.
Alternately, maybe moving portions of Galio's W onto his Ult could work.
Overall, I feel that Galio could lose his Passive and Q, change his E into a Dash or Leap, and adjust his W and R a bit.
sheild and old ult mechanic, 
dive/ tankiness, 
armor affinity and ability effects and 
taunt/Ult) , and 
's Ult is pretty much his bread and butter. If I were to say what parts of him are the most likely to get reworked in order, I'd go with his Q first, then his E, then his W, followed by his passive and the last thing they would change is his Ult.
