It honestly makes me sadface. I've even had two people have the nerve recently to message me just to tell me I am playing her wrong and offer "tips."
I'd appreciate some commentary, and insights, into these subjects of which make me dearly saddened. 
I have been playing her since before her remake and never once have I felt that anything other than AD was appropriate on her AD ASSASSIN self.
I do hybrid since some of her abilities are AP and some are more AD.
She lacks the damage to instantly burst anyone in most scenarios, but her short-ranged kit forces her into a vulnerable position in fights. Building tanky is her best bet to be useful in teamfights and to prevent her ganks from becoming special delivery feeding. Also, her ultimate is decent for engaging from stealth, but tankiness is pretty mandatory if you are going to lead opening teamfight engagements.
You can build her AP, AD, or hybrid by the way. Most people just really want Rylai's since it gives her damage, tankiness, and it works well with her Q and makes it feel like it did before the built-in slow was removed.
The reason people build ap is that all of her damage abilities have ap scaling, whereas only her E has ad.
Yea I mean she can really be built anyway and work if you're good. But I personally think a bruiser build works best, and a AP bruiser build at that I've found quite superior over an AD bruiser build.
So what I am most confused about is people saying that AD Eve can't instaburst...
My last game I took on a fed Kalista and Leana 2v1...
Then later I took them again. I was trying to bd open inhib and the Leona ulted me, I was down to around 20% health when stun ended, I w'd over to the Kalista and Bortk'd her, then instagibbed her and finished off the nexus.
AD Eve has really explosive burst......................................................
More opining please.
You do know evelyn and udyr are the only 2 champs to be through EVERY item build excelling with them right?
