That is a question better suited for the Pokemon Reborn sub-forum, but it was made with RPG Maker, a few Pokemon-based mods, and whatever other wizardry Ame concocted. Anyway, moving on. The Ashe rework has been out for a bit shy of a week now, and I've been able to watch some people play her (as well as get in a few games myself) and I have some first thoughts about the Queen of the Freljord's new kit. Power spike As she does not have the level 1 burst that she did before, Ashe is considerably weak prior to level 4, when an extra point in Ranger's Focus kicks in and her passive slow improves to 11% (31% with Ranger's Focus active). Thus, as you'll see with some math below, Ashe is strong in trades once she hits level 4.
Aside from that, her next power spike is level 6 for the same reason as before. Enchanted Crystal Arrow. 'Nuff said.
After that, her power kinda droops until she buys Infinity Edge because it adds so much to her passive damage as well as Ranger's Focus. I wasn't bothered doing the math, but...yeah, it's a lot of damage.
After that she scales pretty steadily into the late game, where she is about as powerful as she was before. Maybe a little bit more powerful. It's kinda hard to gauge. WTF is this new passive? Autoattacks and spells (Volley, Enchanted Crystal Arrow) slow for 5/11/17/23/29/35% (levels 1/4/7/10/13/16) for 2 seconds. She can not critically strike targets that are not slowed, but she will always critically strike targets that are slowed, dealing 110% damage plus a bonus based on her Critical Strike Chance and Critical Strike damage, based on this formula:
10 + (% of Critical Strike Chance × (1 + Bonus Critical Strike Damage)) % AD
For a quick example, with an Infinity Edge, Phantom Dancer and 200 AD, Ashe's basic attacks deal 385 damage on slowed targets. Now we get to the fun part... Ranger's Focus Ashe's real damage strength comes with Ranger's Focus. Ashe passively gains stacks of Focus every time she damages an enemy with an autoattack or ability, stacking up to 5 times lasting 4 seconds (this is disabled while the ability's active is on cooldown). When activated, her Attack Speed increases by 20/25/30/35/40% and Frost Shot's slow gets an extra 20% for 5 seconds. If Ashe has 5 stacks of Focus, she gains an attack steroid, firing a salvo of five arrows for each attack. Each of these salvos deals damage (total) of up to 115/120/125/130/135% of her attack damage that can critically strike (per the bonus damage from Frost Shot), apply on-attack effects* (such as Runaan's Hurricane) and life steal. (On-hit effects will only apply once). With this and the Attack Speed buff, Ashe can outmuscle a fair amount of the ADC meta in early trades as well as outDPS a lot of the ADC meta in medium-length teamfights. All while permaslowing the enemy front liner(s).
* Pix, Faerie Companion will only be triggered once per attack.
Hawkshot
It's global now and has a charge system. It's very useful for scouting the river and brush, getting timers on the enemy buffs, seeing if the enemy is headed for Dragon/Baron, stuff like that. Other than that, not too much to say; it serves pretty much the same purpose as the original Hawkshot, although you don't get extra gold on kill anymore. Build This is probably going to be the build you usually get with Ashe:
So as you can see, standard ADC stuff. Ashe scales very well with Critical Strike Chance as well as Attack Damage (due to the nature of Ranger's Focus and Volley), so this is the usual build path barring situations where other items are needed. Infinity Edge alone is a really big power spike for Ashe since the AD, crit chance and crit damage combined have great synergy with her passive.
But why the Black Cleaver? If you can initiate a fight with Enchanted Crystal Arrow, you'll get a stack for each person you slow (this includes minions and monsters off the splash damage), which in turn allows you to reach max Stacks with a Volley (or maybe another autoattack right after), which lets you get the rapid fire sooner. As it works right now, each salvo attack fired during Ranger's Focus will apply five stacks of Black Cleaver, which means you can hit the max 30% Armor shred very quickly; as it is applied before flat Armor Pen or Last Whisper, AD caster-type champs like Zed and Lee Sin will very much appreciate the shred.
Not to mention that you get extra HP to take a wayward spell, and 20% CDR to far better take advantage of the utility you have, as well as cope with the painful 18 second cooldown of Ranger's Focus. That Phage passive is really good, too. 10 movement speed on hit doesn't seem like much (keep in mind this also scales with Zeal and its upgrades), but it can be when you have your enemy slowed. The 30 on-kill-or-assist movement speed is also an underrated tool for disengage or keeping up with the fleeing enemy; which is good, because Ashe still has some of the worst base movement in the game.
You may still prefer Last Whisper because of the 5% extra armor pen as well as being 700G cheaper. I wouldn't blame you if you did, either. But as of right now I reckon The Black Cleaver is considered to be the superior Armor Penetration item on Ashe.
Will update this later as more balance changes come to the PBE!
