Time for my yearly Aatrox trials. Quick impressions.

Accessing Hellbent is super important. Starting out that is accessed through the third proc of Blood Price.

Runes:

9 Attack Speed Marks
9 Armor Seals
5 sMR or MR + 4 Attack Speed Glyphs
3 Attack Speed Quints

Masteries:

I've been running 18-0-12 with Fervor of Battle the keystone of choice. You could alternatively run 18-12-0. And some people seem to like Grasp of the Undying so 12-0-18 is another possibility though the later seems to be more lanecentric.

Skill Order

They fixed the healing on his W Blood Thirst at a value that scales with the amount of points you put into it + 6.5% of your missing health, so there is less reason to max this first.

For ganking that means that you should probably level E, Blades of Torment, followed by Q, Dark Flight.

So R > E > Q > W.

His abilities don't cost health anymore so thank sweet baby jesus you can build health on him now.

I've tried a couple of builds on him.

Enchantment: Warrior + Trinity Force is meh. It costs too much and lacks in attack speed until you finish the Stinger portion of TF.

Enchantment: Bloodrazor + Blade of the Ruined King. Again really expensive and for whatever reason it felt like it didn't do that much damage.

Blade of the Ruined King + Black Cleaver, using Hunter's Machete as the only portion of the jungle item. Felt decent.

Enchantment: Bloodrazor + Titanic Hydra. Now this felt pretty good. Will definitely explore this path more. I do feel like you need to finish the jungle item first as the extra attack speed really helps before you can activate Hellbent.

Follow up with a Guardian Angel, Dead Man's Plate, Spirit Visage, and boots of your choice. Ninja Tabi, Mercury's Treads, and Berserker's Greaves probably being the main three to choose from.

Guardian Angel was really handy to have when your passive is down or you get unlucky and don't manage to proc Hellbent during a skirmish or team fight.

Love the additional range you get on your auto attacks during your ult. That change has been around for a while, but I felt like I have been able to make better use of it with this iteration of Aatrox.

The Hellbent mechanism is both a highlight and a low light as it feels great when you get revved up by it and it feels ****py when you are like one step from actuating it and you end up dying as a result.

Jungling is more positionally challenging. You need to kite the camps to keep your stacks on your passive up. If you can do so you can easily do a full clear with really no health problems.

In some ways this iteration is an improvement and in others I feel like it still misses the mark. It kind of feels cludged together. If his passive stacks fell off at the same rate as say Tryndamere's do then it would probably feel better. It feels weird that they don't fall off in the jungle but they do fall off when fighting minions. Makes killing super minions much more of a chore.
