You should get one rank in Null Zone before level 6, because it's an essential part of your Hadouken combo. And the reason that there is no love for MET is because it's outclassed by DFG on most offensive casters.

Also, Abyssal Scepter outclasses Void Staff for the most part, given the runes/masteries/boots you've purchased.

your only justification for buying morellos tome is that you like it over DFG - and they are both extremely lackluster item choices on Malzahar compared to rylais, deathcap and zhonya's hourglass.

hell, you could easily get a rod of ages over morellos / deathfire, or just the catalyst for your banshee's for lategame (or needless for zhonyas)

seals are bad (rofl flat health, mana/5/lvl > health/lvl > flat health), your summoner skill choice is bad (you can easily fill your mana off of level 3 malefic on one minion wave, so clarity is out of the question)

for the guide itself, it's extremely difficult to read (spacing helps, you know, so does formatting).

tl;dr the guide, read parts of it. your items are generally bad, your order is outrageous, you have no defensive items, so have fun getting decimated by any competent nuker / dps.

it's not trashing MET, it's trashing the guide in general.

Well I agree that the AP it provides is fairly low, however as you stated I can't place it in front of Rylai's or the Hat. However I do believe there is a point as I described which is that with multiple Malefics ticking for large amounts of damage on top of the other skills you are throwing, the spell vamp is very useful. I am also a huge fan of building aura items late game, as a team with multiple champs that use AP will also be gaining a benefit of 30 AP and 20% spell vamp from will. This is simply an agree to disagree moment, I would also respect building other items like lich bane or even an archangels later in the game. I also do not follow this build very closely late game as I mentioned its extremely flexible. :)

i don't agree with the items you have chosen, but I do like the decision for the skill points.... null zone is overrated early game, and with the cap on damage - better off with malefic. I'll agree with that, for sure. I laugh at malz's who go out of their way to throw up a weak null during their ult midgame when a pumped malefic would have served a better purpose.

the strat you give is detailed, but i think the item selection is not a good idea... getiing will of ainchents that late in a game is universally regarded ads a bad idea... it needs to be built early, like around the position where rylais is in your build >.< but rylais is super important on malz, so you cant push that back either...what i am saying is it has no real point in here this late =[
edit - yes sorry that is the item i was reffering to - sorry for the confusion they have similar pictures 0.0

I did extremely well with this build. 11-4-5. Extremely detailed guide ftw.

OMG WHY WOULD YOU GET MORELLO'S, GG MAN, WTF

I kid, I kid... but yea. Works for me. +1

TLDR. But really good information overall.
