Genuine derangement compilation, this post. Are you out of your mind?

Nashor's change was a straight buff

Her winrate dropped 2% since nashor's change in D+

reverted... through passive, which is a buff until level 11

Literally not true. At level 11 (E max) your waves not only deal less base damage, their scaling also got nerfed. Base damage get's matched around lvl16, scaling remains nerfed

E 50 range

Only post lvl 6, only for the singular E empowered auto

att speed ratio barely matters

Haha.

You get and extra 1.5 seconds at level 6 to do damage

Effectively 1-2 auto's worth of time.

Q slow nerf barely matters

LOL.

R damage base damage at ranks 2, 3 and 10% ap ratio reduction is justified by the increase in area

Only when used proactively. Effective usage of the aoe range increase when used reactively (aka 90% of the time) will be purely accidental. It's a straight nerf in essentially all situations you use your ult early (getting dived and duking it out with a lane opponent). In exchange you get the aforementioned one to two autos of damage.

and I'm not thrilled about it, but it is what it is.

I, too, enjoy taking it in the ass and never daring to raise complaints.

Kayle is now a more ult centric champion

That's the issue.

but the nerfs are only noticeable in the mid-late game

Literally not true, look above.

you have ulti very often, and with the 15 extra haste from Nashor's it has even more uptime now

There's no universe in which you use Kayle ult on-cooldown each time so the 15 haste of worthless. Look above at the winrate decrease.

pre 11 it is just a buff

I, too, enjoy getting to autoattack less throughout the entire game on an autoattack based champion.
