I like this build but find getting Madreds before Rylais a little dumb. You aren't meant to deal massive DPS, but the slow offers you way more utility.

I just don't see how this build could possibly be viable. I was playing a 5v5 on Twisted Treeline and I played Blitzcrank with this build, and overall I don't think this build enables you to survive all 5v1 situations which is my core play style. Maybe if you built him more like a "Junglesticks" (Fiddlesticks in jungle), you could possibly tank the entire team and win.

i used this build and went 5/1/18 in my first game as blitzcrank. great build man +1
