Galio needed buffs/changes

I believed in Galio until I went against an actually good Zed and realized that Galio is too crippled by mana costs before chalice to stand a chance against Zed or any other manaless champ with decent waveclear really. And yes I know, physical damage dealers are supposed to be good against him, but the thing is that Galio actually never had problems because of the damage type his opponent deals. It really comes down to mechanical things. Ironically if Galio is not pressured early or just plays impossibly perfectly early game, his mechanics counter Zed's mechanics. But due to numbers he has a huge disadvantage in this matchup and too many others.

Chalice costs more than it used to, which hurt Galio a lot because he is absolutely crippled until he gets chalice. Also, the fact that Chalice regen is not as good until you also invest in mana pool hurt too. The result is that Galio is weak for a longer period of time early game than before. And he wasn't even considered good before.

So here's what I suggest.

W - Now costs 0 mana, but gives damage reduction instead of resists. The reasoning is that he'd be able to conserve mana early on by using his shield freely to regen off minions and mitigate damage. The reasoning for changing it to damage reduction instead of armor/mr is so that it doesn't buff his ability damage anymore. This is a very unexciting place to have power in his kit, a button you mindlessly press to deal slightly more damage. Instead, it should just give damage reduction and cost no mana.

Another suggestion, but is a much bigger change, would be to remake his passive into something completely different and build the MR scaling directly into his abilities. It would help him alot and allow for a more gameplay-oriented passive while putting the MR->damage thing into his abilities just like Malphite or Taric with their armor scaling abilities. If this is done, a passive that helps Galio lane early would be pretty nice. Anything to make it so he doesn't have to rely as heavily on his abilities early.
