Hello there. I'll try to offer some constructive criticism. You must be aware though, that I also downvoted your guide since I think the whole idea is bad.

Reasoning: Blitzcrank is bad for a solo lane. He isn't really meant to do anything else. Jungling isn't an option either since again, he is bad at clearing, a bad duelist overall and would be very vulnerable to invades.

If I ever would pick him for a solo lane, it would be mid. And I would go with an AP build. Why? Because Blitz's potential relies on gibbing people, not in prolonged fights. Your build is for a bruiser, not a burst caster (the way a Blitzcrank could be played with some degree of efficiency).

And even so, I wouldn't play him mid because he is melee, would have a bad time farming against most matchups and if you miss the hook... Well, you can't do anything.

This is why you are being downvoted. Main two reasons: 1) You're trying to play a champion in a wrong way, wanting him to become a duelist when he's a combo champion. 2) The guide is short, not well explained. The choice of AD scaling runes is particulary bad as well (everyone plays them flat, there is no point on scaling AD).

Make some research and try some more feasible picks.

pepsiM4A1: Ok then, i can do a real guide, looks like fun build are not tolerated. On MF are so many fun builds , and i know that its waste of time for some people. I will archive this (Know how its going on MF, you cant delete guide withoud admin help, you can just archive it - so only people that have link can see it)

This is why MOBAfire's reputation is such a.. how can I call it? Noobish? Other people come, visit these "for fun" guides and then they think MOBAfire is full of such "for fun" guides, and it is. Please, a guide is made to teach someone how to play a champion, not to screw them over with your questionable fun. YOU don't even know how to play Blitzcrank or any other champion, then why do you come and lecture people who are actually good at this game? Please, for the good of the community, delete this guide...

I still do it; for fun.

It's not competitively viable by any means.

don't say something against ap varus. it really works and is awesome fun :DD

I should, cause this build is for fun. And everyone who rated is taking it too seriously. If you dont read guide introduction, i dont care. I want from you to vote it as FOR FUN build. Meaning of this build is that you will have fun when grabing enemy , thinkin' "Hah! You cant run from me!"

yeah you shouldn't say that

Downvotes, i dont care!

Guidewriter, meet downvote!

This is like when I was new to mobafire and trying to pawn AP Varus on everyone with almost the exact same arguments OP has;

"It really works try it!"
"It's for team fights!"
etc.

lol.

That can go unsaid. If you don't have something useful to add in the way of the discussion, you should really just keep quiet :/.
