Lacks BB codings ._. Suggest you to read jhoijhoi's Making a Guide(it is actually the "Guide Help" in the guide edit).

<< ???O.o you sure? You sure you eill 100% hit them? O.o Well even if you do others couldn't, Mejai's Soulstealer is optional, means that if you own early game then you could get this, if you don't....don't, ever, get, this, item.

Wall of texts....

You should max Mystic Shot first, you may say something like: " Essence Flux deals more damage with AP! So I max it first !!!! " Sorry bro....the reason to max Q first its because it is his main damaging tool and his W has a high cooldown.

For the cheatsheet, its kinda fine but can you just move the mejai's to Optional Items??? Cause if you don't own the game early, it is useless...Remember to mention trinkets.

As for runes, I suggest to you to add situational runes for AP and AD Ez:
AP: greater mark of hybrid penetration for dealing more damage with your AA and/or let you easily farm minons.
Greater Seal of Armor, if you lane against some popular AD Mid lane like Zed and Yasuo.
Greater Seal of Mana Regeneration This helps almost all mid laners(that use mana) to use their abilities often.

AD:
Greater Glyph of Magic Resist against some popular AP supports like Annie.
Greater Quintessence of Life Stealx2 Most AD take these =/

Grammars.....Erm...just redo your guide.....

The builds are OK but I don't feel like giving an upvote to a guy who misspells the title of the freaking guide.

you have to buy some CD reduction and you have still to spamm mystic shot so you need also lot of mana regeneration and it's true this is one of the main reasons why every one is playing AD eze but AP also make fun i play both but i also have to say I also like AD eze more

So I mostly play AD eze and follow this guide, but I tried the AP-guide and I must admit I quite a noob and don't really know how to play :P But the main problem I find is the CD. When I go into a fight even with the team I can only cast a few spells and then I'm useless for like 5 seconds at least.. how do I counter that?? (apart from spamming mystic shot)

o_O better than me xD
im a ad eze but ap also is cool some time ^^ so i gave my best to do a good guid for a friend^^ did my best and it worked ^^
