Not fully done but this is one hours of me putting out my thoughts, please put in constructive criticism but I would rather you not vote yet, but you can if you must, but enjoy till then.

Hi, I'm Qfish ere with my first build on Moab fire, so any tips would be greatly appreciated when it comes to this, or you can tell me anything that you want me to add, and I'll test it out then hopefully post it within a week at the most. Anyway here is my guide to my faviroute way to play ez. Ap if you haven't guessed already. when I started out playing lol back in 2011 I didn't know what I was doing, AT ALL, buying whatever the hell I wanted - e.g. Ap on cait or flat attack speed on malphite. that happened until I picked up teemo and then looked a phreaks guides, then I understood (not). but anyway not long after that I pick up my second champ ez. when I first looked at his skill ratios I thought he was an ap. so I started playing him that way even till today. it has been about 2 and 1/2 years of experimenting to get me to where I think this build is just right. but do note I DO NOT recommened this build to anyone who can't land skill shots or love to play master yi (mainly because I can't play master yi or tryndamere). you must be able to know how far you can go in if you were to play this in ranked (I got through bronze, into silver then into gold with this build, so I know it works) but anyway enough of me blabbering on and lets get on with the build.

Pros:
Extremely high burst damage to entire teams
Capable of blowing many mid laners to shreds
nice poke
nobody will think your going ap
he hates noxians like darius

Cons:
No cc
squishy pretty much throughout the game if he doesn't have someone to protect him
his taunt actually works ;(

these runes I chose because they give him some resistance against ad which is his main weakness early but do give him the capability to scare of ganks with his high damage out put even if he is facing someone who's brought Mr runes thanks to the ap quints and gylphs and MP marks.

these masteries I chose just because they sinergise well with his play style of being a buuuuuurrrrssssttttt mage. it also has mana and manaregen so you can keep firing your W.

these items I chose because it mean that the enemies cannot stop your damage even if they buy one mr item. with these items you'll end up forcing the enemies to waste a lot of gold buying as much mr as possible instead of damage.

this should be your general sequence as you shouldn't have to work on your q for little to know improvement since your not going ad. you can change it if enemies are playing to smart to get hurt by your e.

for ranked play I would not recommend this until your happy that you can play consistently and not get greedy, as If you do you'll end up cost your team the mid lane and/or a loss. so DON'T get GREEDY.

as ap ez your want to follow up all initiates done by your tank ( but only if your hitting at least 3+ important enemies e.g. enemy adc, mid laner and support or top) then make sure to get behind someone who has some cc then just poke until you can jump in for the clean up. (or if your that far ahead that once you ult though them you could probably e and w for the instant penta - which you should be able to do - but remember don't get GREEDY) in short your goingf to be able to duel anyone and practically deal a tonne of damage in a fight but you will die if a master yi ignores everyone and hes really fed and he dives on you. (from that it means fed yi + enemy ap ez = dead ap ez) but you get the jist, base your team fight off what your capiable of doing at the time and remember don't flame your teammates you need them to protect you when you do stupid things.

farming is very important (as always) on ap ez as your probably not going to start racking up your kills really quickly until levels 6-9 ( this was an accident that I can't fix) but even them you must try and keep up with your cs and use your q often if you've just used your ujlti as that cd that you get from that is nice. in short just farm and get your items ( make sure to poke with your w) then own everybody.

you combo should be e in, w, q and then ulti to kill someone ( dfg at the start if you have built one) ( oh and make sure to hit the skills)

in summary enjoy this build, its a lot of fun and you will surprise allies and friend and maybe even some enemies. but don't get GREEDY, make sure to land your skills, remember to farm with your q and autos and poke with your w but don't spam your abilities so fast that you run out of mana and have a good time.
