Standard Mana-Intensive AD with meditation
These runes for every AD carry,nothng to say
Focus allows for many interesting tactics at level 1. Having a crit at level 1 and Volley allows you to burst someone instantly for around 250~ damage, this combined with a stun can be deadly. Ashe is one of the scariest champions to deal with at level 1, as she can invade or defend against invade easily. Camping a brush early on and getting off your early burst can also instantly win you the lane.
Frost Shot allows Ashe to kite, since it's on her Auto and Volley, it makes catching an Ashe essentially impossible if you don't have Flash. 35% Slow on auto's just scale incredibly well into late-game, imagine a Sion without flash trying to kill a late-game Ashe... It's just impossible unless she gets caught.
Volley is insanely strong level 1 - 3, then becomes sort of weak since the base damage increases on it is horrible. However the cooldown reduction you get when you level Volley is amazing, allowing for an almost permanent AoE slow combined with Frost Shots.
Hawkshot is maxed last, even though it gives extra gold while killing creeps. Hawkshot is a great scouting tool, incase a ward drops on Dragon/Baron, or if you think you're getting ganked. Hawkshot is also a great play-making tool allowing your jungler to gank easier or hitting a Crystal Arrow.
The extra gold is really nice if you're killing Wraith camps, since the small ones give you so much more gold.
Enchanted Crystal Arrow is one of the best initiations in the game. It can completely swing the game around in your favor if you can land this ultimate on a critical target, or catch enemies offguard or in transition.
There are some simple rules for Enchanted Crystal Arrow that I tend to follow.
1. Never hesitate
2. Try to time my enemies last hits/abilities
3. Try not to go to "across the map" arrows
4. Never engage a fight after a missed arrow
Try and force something with your level 1 burst, either invade or camp a brush, or simply secure double golemn advantage.
Play aggressively if you can during the early levels, but realize when Volley's damage falls off and go into farm mode.
Once you hit 6, it's very easy to set up ganks for your jungler, be patient and communicate.
Most AD's are stronger than you at this point, so be careful when fighting for Dragon's.
Try and pick off someone with Arrow and then secure Dragon, don't do anything silly when Arrow is on CD.Just Farm,farm,farm!
This is when Ashe becomes a monster, because a good Arrow will simply end the game. Gain ground with Hawkshot and completely focus on landing good Arrows. If you still need your last couple of items such as QSS or LW... Hawkshot's extra gold will make it that much easier to get them. Don't be afraid of late-game, since Ashe is one of the strongest late-game AD's, 35% AoE perma slow is simply too much for most melees to handle.
KITE! You wan't to be able to move in between auto attacks and Volleys. Make sure you land Volleys on the crucial melee champions you want to be able to kite.
In most scenarios you want to already be at an advantage before engaging into a full blown teamfight, since you have the option of initiating whenever with Arrow.
Hawkshot is also very good for team fighting, having vision will allow you to kill enemies that are trying to avoid being hit in by sitting in brushs.
Ashe is a defensive AD thats very strong late-game AD, but is also incredibly strong at level 1. Her early-mid game is extremely weak due to Volley scaling, but her ability to initate is unrivaled. Being able to land solid Arrows is simply very rewarding, which makes Ashe incredibly fun to play.
