The formatting makes it really hard to read. You need to make better use of graphics, headings, white space, etc.

What really bothered me is how ridiculous and insulting your reaction to the constructive criticism above was. That attitude tipped me from giving you the benefit of the doubt to downvoting.

If you clean up the guide and apologize to the poster that you flamed, let me know and I'll change my vote.

+1. Well written, no clue why this was downvoted. Just might wanna add some codes to the spells and champions. Also, you should probably make builds for each champion.

why dont you look your job
fool!!!!!!!!!!!!!!!!!!!! go and talk to peopl like you (with 2 or 3 posts)
loser!

You should rename "Mages" to "Nukers" (also there are physical nukers aswell) and rename "DPS" to "Carries".
Also its "Masteries" and not "Masterys".
There are some insane walls of text at different chapters (for example "Items 2 recommended items with on-hit effects") that are extremely hard to read.
In addition there are champions that just simply can't be played well without good game experience. I would say you should remove those from the guide:
Anivia
Twitch
Caitlyn

Also they all cost 6300 which is too much for one champion for a beginner.
Brand is also an expensive one but he can be learned fast.
