DO NOT BUILD EVELYNN AP (Read before downvoting)
I am open to all debate and will reply to everyone
Ever since i played the new 
I felt like something was seriously wrong. So after a couple games I did some stat digging and went to the lab.
Evelynn is NOT an AP assassin anymore, her kit is that of a TANK. (HEAR ME OUT)
To back up my theory I had to compare her to a similar AP melee character, 
The information below is ONLY BASE DAMAGE
Maokai
Base AD - 64 , 67, 71, 74, 77, 81
Base HP - 572, 662, 752, 842, 932, 1022
Base Armor - 30, 33, 36, 39, 42, 46
Q - 70, 115, 160, 205, 250 W - 50, 75, 100, 125, 150 E - 25, 50, 75, 100, 125 R - 150, 225, 300
Evelynn 
Base AD - 61, 63, 65, 69, 70, 73 Base HP - 572, 632, 696, 762, 832, 904 Base Armor - 28, 31, 33, 36, 39, 42
Q - 130, 180, 230, 280, 330 W - 2 second disable, 25-35% MR reduction for 4 seconds E - 30, 45, 60, 75, 90 R - 150, 275, 400 / 300, 550, 800
's kit is more attractive to a tank role. She has HIGH base damage on her Q in the early levels, meaning you can sacrifice AP for health/armor, and start off with a 
for disgusting early trades. Her Q is on a lower CD, and has higher base damage than 's Q at all levels.
Her E, as her second max, deals % Health damage something champions like 
are known for, and compared to 's E, she beats him in % Health damage after 100 ap, AND can cast the ability twice out of stealth.
Her W, the last max, but ability that puts her in the tank role in my mind, is a 2 second disable, that takes 2.5 seconds to ramp up. If you were to use this in the assassin role, you're telling your target "HEY I'M COMING FOR YOU, YOU BETTER BACK UP". Something that is INCREDIBLY attractive to a tank, NOT an assassin. Being a much less bursty, but being a lot better a sustained damage up close, people in a teamfight or skirmish aren't going to go "oh fuck, evelynn is about to one shot me, better use this 2.5 seconds to get away" (which is incredibly effective) they're going to go "oh i'm marked, and i can see evelynn, i'm fine". you walk up to them with hate spikes and charm them, giving your team effective CC.
Her R, although isn't a very team oriented ability, gives you an EXECUTE, much like 
or 
. This also removes you from the fight in that instance, and gives you time to recover and move back in. This can also be used as an initiation with range similar to 
Q or 
E+Flash.
Her E Also gives you % movement speed on cast, keeping you sticky.
So what do a build on if she is no longer an assassin? Simple!
Remember how completely aggravating and impossible to deal with 
were? Now you get to use it effectively on .
Compliments her base damage on her Q INSANELY well, making you seem weak, but SWIFTLY racking up a lot of damage in a skirmish.
Compliments her melee range. Keeping her close with a slow, dealing more base damage, and gives you CDR so you can Q+E even more. (Remember, E gives you movement speed!)
Compliments her need for MR, and provides more CDR. When your passive kicks in to heal you when you're close to death, you gain it back FAST, and can move back in for a kill.
Helps with your initiation, MORE BASE DAMAGE, and overrall helps you get around quicker.
Are the cherry on top. you can build 1, or both. gives you % Health shred, and .... you guessed it, 300 more HP and 80 AP. while provides a slow on every hate spike, and gives you... EVEN MORE HP!
"But Scurvy..." I hear you saying. SAY NO MORE. Your keystone is no longer Thunderlord's Decree, From now on, you will be building your mastery tree 12/0/18, with the keystone Grasp of the Undying. It provides more % Health Shred and gives you Sustain, something tanks also enjoy. And in the rest of your tree you will want whatever gives you armor, health, and damage reduction. on the ferocity side, grab Ability % damage, and battle trance, to ramp up your damage in prolonged skirmishes.
And there you have it! you can ditch the troll AP build, and start charging around on your 4 second cooldown stealth TANK. and don't worry, in lane you can pop your W on someone when it looks like they want to trade, and come out victorious once you've charmed them and responded with % health shred and high base damage on your Q.
Evidence gathered since post:
In her recommended starting items as a laner, she is recommended 
shield to start

work? He has even less CC: this time, only on his ultimate, which is honestly more reliable than Eve charm but on a much longer cooldown. But again, he is much stickier than Evelynn. If you try to slow him, he'll just jump forward, and then dash through you to the other side, and then jump again shortly after. It's so hard to get a high CDR Fizz off your face.
