This is very important
It says it procs on hit effects twice, which we could assume means he gets his Heal twice or his Damage twice. I'll have to test it on the PBE, but honestly it should work this way. Give Jungle Aatrox some sort of reason to be picked.
Erockandroll1 votesMy guess is that it will speed up how often he procs his W passive, I don't imagine the passive procing twice in rapid succession.
RiotMeddler5 votesThat's correct. Aatrox will proc his W effect every second attack, instead of every third.
Kingsgrave1 votesThat's correct. Aatrox will proc his W effect every second attack, instead of every third.
That's fine actually. Pretty large buff. Loving this item. Only really worried about how dangerous it's going to be on Yi and how that might ruin it for everyone else.
I wish Aatrox's W damage was Magic to fit more in line with his E damage, but that's just me.
Would also be nice if his Passive decay timer was longer so he could jungle better. 5 seconds makes him decay too fast inbetween ganks or camps, so he never has his AS up.
Be even better if Riot finally fixed his Q bug with Scuttle Crab. Displacements are supposed to lower Scuttle resists but Aatrox's Q doesn't.

Screw Yi, he'll still have the same problems as always. I'm worried about Fizz.

Yi can reduce his Q to effectively 2 seconds with this item
TheRakkun1 votesGet out the way Fizz, Vlad and Fiora, we've got another annoying invulnerability champion coming through... Again...

too bad his q cots 110 mana
Roaranor1 votesWill it alter empowered autos for champions like Diana, Xin (specifically his Q knockup on third hit interaction), Draven Q, Vayne's Silver Bolts, and Riven passive the same way it does for Aatrox?

Probably.
Any 3 stack mechanic will become a 2 stack mechanic with this item.
Makes me really worried about how powerful it will be on 
Pit Fighter Sett1 votesExactly the phantom counts as an attack for those stack mechanics; if I understand Meddler in this.
But like replied above Udyr would have permanent Fire Cones on each basic attack in persistance eagle stance; which seems soo broken to me.
qetzel1 votesIt might not work if the skill is an auto attack modifier (Nasus' Q, Xin's Q) rather than an on hit.
I would guess that that is why Kayle was altered on the PBE. Previously the damage was counted as part of an attack modifier, not anymore.
Pit Fighter Sett1 votesThought I figured out how it worked; being really strong on Yi (E) and Irelia (W). But in this case; how does it work on the 2nd Hit? Does the phantom count as basic attack for the counter toward those 3 hits to proc the skills' effect? Or does the phantom and not aatrox himself proc the skills passive when aatrox is doing his 2nd basic attack while procing the phantom which then procs the third hit. (in the last case aatrox himself wouldnt proc the skills' passive)
Wouldnt this meen Udyr with PERSISTANT eagle effect(which does the fire cone every 1st and 3rd hit) being able to do like fire cones on every basic attack O.o????

Jax R applies every 2nd auto instead of every 3rd Diana passive applies every 2nd instead of every 3rd Udyr R applies every 2nd auto instead of every 3rd
etc.,
Cindikle1 votesHow does this interact with on hit abilities like Ezreal and Fizz's Q?
Can they AA a target, then use their ability to proc double on hit damage? Not that either one is a very good jungler.
