Galio's scalings are WAAAAY too high.
It might not be noticable with his play ratio, but if he goes full AP, his damage is insane and there is very little counterplay. His Q range is quite high and hitting it means 50% HP gone on any squishy, not to mention you can't really dodge his E with range that high, it's basically an 8s CD Malph ult. He really needs to get looked at and if it won't happen now, i guess we'll just have to wait until they abuse him in LCS for RIOT to notice it.
