Kayle will be the most broken champion in patch 5.13 (2000 aoe dmg/second)
New: "Passive: Kayle's Basic Attacks deal an additional 10/15/20/25/30 (.15 AP) magic damage on hit. Old: Active: Kayle increases her Attack Range by 400 for 10 seconds and the passive bonus is increased to 20/30/40/50/60 (+0.25) magic damage on hit. In addition, enemies near her target take 20/30/40/50/60 (+20/25/30/35/40% AD) (+0.25 AP) magic damage on attack."
Now becomes "Sated " at 30 stacks. Base magic damage on hit increased to 30 from 25 Passive Changed to "Devouring Spirit" - Takedowns on Larg monsters and champions increase magic damage by +1. Takedowns on epic monsters increased by +5
Sated: "This unit's Devourer is Sated. Basic attacks deal X bonus magic damage and every other basic attack will trigger on Hit effects twice."
Let's take a look at kayles build:

This means that every second attack will deal
120 magic damage
16% of current health
84 magic damage and remove 10 magic resist
10 % armor shred
From those 4 items.
Then her kit: Passive: 6% magic resist and armor shred E Passive: 60 (.3 ap) magic damage E Active: 120 (.5 ap) magic and 120 (.8 ad) (.5 ap) magic to those around the unit being attacked
This is a total of 384 (.8 ap) magic damage plus base ad plus the armor shred. (Not sure how shred stacks).
And now we go to there fun part.
This means basically every single attack is going to be a sated attack and will apply to 3 targets. Plus kayles has 2.5 atk speed with this build. So in ONE SECOND you will be dealing around 1500 mixed aoe damage. (Too lazy to do exact math and it depends on event stats) I see this becoming very problematic but also extremely hard to balance because you can't just nerf kaylee or devourer because then those will not be good. They could make it so sated bonus doesn't attack with hurricane.
Tldr: around 1500 mixed damage a second late game.
All this stuff just got on the pbe in case you don't read surrender @20.
edit: calculated damage wrong [she does more ;(]
makes 3 attacks: that means either the first and third are doubles or the second one is a double.
The Damage that will happen in one second. (Without shred)
First hit: 192 (.4) magic+100 physical (base ad) +8% current health physical
Second hit (runaan bolt): 384 (.8 ap) +100 physical +20 physical (from runaans) +16% current health physical
Third (runaan bolt): 192 (.4) magic+100 physical (base ad) +8% current health physical +20 physical (from runaans)
First:384 (.8 ap) +100 physical +20 physical (from runaans) +16% current health physical Second (bolt):192 (.4) magic+100 physical (base ad) +8% current health physical +20 physical (from runaans) Third:384 (.8 ap) +100 physical +20 physical (from runaans) +16% current health physical
Sum it up: 1344 (3.6 ap) (3.6 ad) + 660 physical from base ad and runaans + (53.8% of health ) botrk physical damage per second. (assuming you are hitting the same 3 enemies every attack.)
Q or
's R(i think), it only procs on basic attacks, which is why a lot of people are complaining about how bad it will be for ww
who will become insanely OP according to others if jungle Yi isn't nerfed in some way, or the item changed
