Thank you, i'll use your Tips! It's also my first guide so :D

1. Your cheat sheet is very confusing, you don't talk about runes. The items are all messed up, try to break it into small parts: Starting Items 1, Starting Items 2, Core Items and etc.
2. About masteries: Expanded Mind is useless because you wont build a big mana pool, this gives you 3 more points you MUST put a point in Culinary Master it helps so much! And the other 2 points put either in offense, so you'll be 9/0/21, but I prefer 0/9/21 for Blitzcrank.
3. Very far from being completed, archive it because people will come and downvote for that, no need to rush your guide.

Well you only just published the guide but lemme give you some tips.

1. Better to not publish the guide until it's rather finished to prevent people voting it down because, you know, it ain't finished.

2. Champion Lores are useless to your guide. You can however add a link:
For Blitz that could be [url=http://leagueoflegends.wikia.com/wiki/Blitzcrank/Background][i]Blitzcrank's Lore[/i][/url]

3. Try to use columns.

I.e. About Blitz:
[columns]
[nextcol width=375]
[center]
Health 423 (+95)
Health Reg. 7.25 (+0.75)
Mana 200 (+40)
Mana Reg. 6.6 (+0.5)
Range 125 (Meele)[/center]
[nextcol width=375]
[/center]
Attack damage 55.66 (+3.5)
Attack speed 0.625 (+1.13%)
Armor 18.5 (+3.5)
Magic res. 30 (+1.25)
Mov. speed 325
[/center][/columns]

Then you get:

Health 423 (+95) Health Reg. 7.25 (+0.75) Mana 200 (+40) Mana Reg. 6.6 (+0.5) Range 125 (Meele)

Attack damage 55.66 (+3.5) Attack speed 0.625 (+1.13%) Armor 18.5 (+3.5) Magic res. 30 (+1.25) Mov. speed 325

4. Keep your titles a little smaller. There's too much of a contrast now.

5. Toggle C2V. In the upper right corner when editing the guide. (prevents trollvotes)

Best of Luck,

Foxy
