I agree.

Not even going to bother.
Guide is just terrible in general.

Along with the bad runes, masteries, etc. Your skill sequence is also bad. You never max Null Zone first. Always max Malefic Visions in lane. Null Zone is honestly a waste and should mainly be used under the target that you use Nether Grasp on. This guide has been punished enough so I will not vote.

Aside from the runes+masteries debacle, the advice given out in the teamwork and skills sections is actually pretty valid, its just a shame you came after a pretty horrible quinn guide otherwise you wouldn'tve been bashed so hard.
As for the BBcoding thing, you can find the basics here: http://www.mobafire.com/league-of-legends/build/making-a-guide-101506
You dont have to use everything thats there, just take a few simple things from it and you should be able to spruce it up nicely.
I'll come back later to give my vote.

Ok some improvements.

Guide suffers badly from walls of text, use some BBCode to make it look better and make people want to read it.

Runes are very squishy and have too much scaling. I would say armour seals, MR glyphs and then magic pen marks and AP glyphs.

The items are also very squishy. Malzahar can't burst people down so he needs some more defensive items to stop himself just dying. On the other hand this guide looks like it is designed around a glass cannon. It doesn't seem like anywhere near the best way to play him but it is your guide.

21/0/8 masteries. What happened to the last point?

You are missing a summoner spell sequence.

I couldn't really find any problems with the text.

The writing in this guide is quite good but there are a few problems with the main part of the guide and you have no BBCode. Apart from that it seems good and I feel sorry for you because everyone has gotten a bit grumpy and have just downvoted for little reason so I will upvote it. +1
