Galio used to be my main champion and a core build item used to be the Athene's unholy grail.
With the changes to Athene's unholy grail it is a waste of gold to build on Galio now.
Because Galio's W (bulwark) doesn't count as a shield/heal, it won't used the stacks to heal yourself or an opponent.
With all the champions getting a rework, i feel like Galio has been left out and has been underpowered loads.
I feel like a reduced spell cost or higher base mana regen would partially fix this, or perhaps turn Galio's ult back into it's old form where it can't be cancelled when channeling by so many champions.
