Also +rep'd you for your great advice. :)

no problem (: +rep'd you for being open to constructive criticism and for being a good example of how to reply to such comments on builds.

Thank you Haedrix, Im not offended at all.
Actually, I really appreciate your advice and will take it into account when I have time to re-write this guide. I dont really play AD Malzahar usually, thats why its build its not totally updated with items as the the black cleaver. Thank you again.

For the AD Build Masteries, you really still need the 8% Magic Penetration. A lot of your damage is still magic damage and you already put 4 Points in Blast anyway. I can understand not feeling the need for Executioner . Since you do take Ignite on the AD oriented build, I highly suggest taking Summoner's Wrath since it gives you +5 AD and +5 AP on Ignite's CD which you benefit from both.

Meditation is a necessity on AD Malzahar. You have to spam in order to get your tears stacked and in order to keep 2-3 Voidlings up. Wanderer = not worth losing the mana regen.

Brute Force and Sunder are much more attractive Mastery Options for AD Malzahar than some of the points you showed as well /=

Last Whisper is great on AD Malzahar but I would still get The Brutalizer before it. Also, Black Cleaver is a much better upgrade for AD Malzahar than Youmuu's Ghostblade. You do not benefit from the Crit chance or Attack Speed, as neither of these things affect your Voidlings' DPS. Ghostblade does give you more flat Armor Pen, but your Voidlings deal PHYSICAL DAMAGE, which means your voidlings' auto-attacks apply the passive armor shred on Black Cleaver.

If your defense is the extra 10 flat armor pen ghostblade gives you then I'm confused why you are still running magic pen runes?

Trinity Force is too expensive with too many stats you don't need. I'd much rather see a defensive item. Frozen Heart, Rod of Ages, Iceborn Gauntlet, Banshee's Veil would all work better. If you want a really expensive damage item, Hextech Gunblade would be a much better slot filler.

I can see that you tried to make a guide that covers all of the aspects but I think this needs a lot of work (no offense).
