Suggested build path change for Warrior
There isn't a reason for Warrior to build out of Brutalizer. I'd hate to remove Brutalizer from another recipe, but realistically, no jungler really builds it. (unless for Youmuu's)
Ever since 5.2, the combine cost of Warrior has been 63 gold. That 63g is going to give you 20 AD. Doesn't make much sense, does it? No one is going to go back to shop for a Brutalizer being 63g short of an extra 20 AD.
A pretty simple change I recommend would be to take an approach similar to the buildpath of Lizard Elder in early S3, which built out of Spirit Stone and Pickaxe.
(450g) +
(875g) +
(360g) + 165g =
(2250g)
Allowing Pickaxe to build into Warrior allows for a more efficient purchase early game, makes more sense as a build path regarding the amounts of AD you get before and after completing Warrior, accentuates Warrior's early-game threat more, but still allows you to buy some early AD even if you don't have 875g.
Warrior's purpose, to provide early game threat but scale poorly, doesn't currently equal the benefits to safely scaling with Cinderhulk (even though it has a considerable power spike upon completion). I don't just want to just compare it to a more viable option, though. The build path generally just doesn't feel right in my opinion.
It feels a bit lazy for Warrior to build out of an item you'll never even purchase, while needlessly cutting the efficiency of your early game itemization.
tl;dr: Change Warrior's power to be more accessible in build path if you can afford it, instead of exclusively on completion.
