Honestly, my only complaint about Galio's reworked Kit
Is that he doesn't build a lot of AP anymore. Like, he's supposed to be a Battlemage/Warden hybrid, yet Full tank builds seem to be the best way to build him.
I suggest changing up some of his scalings so he's actually enticed to build a fair bit of AP since most of his old mains liked him with a bunch of AP items.
His passive, colossal Smash could use an increased AP ratio as well as maybe making his W and R damage reduction scale a bit with AP so that he can still build stuff like
without completely gimping his build and role as a Warden.
