On a side note the best Ashe build is
, you can't tell me otherwise!
I never mention it. Unless of course its Teemo. Then I explode inside and then virtually scream about through the use of capitals and many exclamation points in chat.

I hate people that build like this. Of all the things why THIS. It isn't optimized for any part of your kit and because Teemo's ratios suck on some things and rock on others you can't just build for everything, it doesn't work.

Covers assassin Teemo, generally the best Teemo at the moment. At least, in my elo where people are idiots and let me drive by their ADC.
I've been tempted to watch that Kotoura-san, but I don't think I'd enjoy it as much as the abridged series.
Then again, sometimes building a champion differently isn't a bad thing. If I prefer playing and play better with AD Bruiser Evelynn than AP Evelynn, who are they to judge me?

Stop rushing

Stop doin' that
Because ya know this is the best build path for everyone
