This will be my first guide, so i hope people enjoy it. i appreciate all reactions good or bad since it will help my guide and my own gameplay.

So please dont downgrade me if you simply dont like it. try to help me instead :D

I choose for the runes:
Greater Mark of Desolation
Greater Seal of vitality
Greater Glyph of Malice
Greater quintessence of Malice

I choose these items since Ashe is squizy, so the hp will rise with each level by a good amount.
The critical strike is always handy to have as AD ranged. and the attackspeed for easier farming.

For masteries i choose 21 - 9 - 0

Purely Damaging with some additional HP.

i choose for the items as much as possible for attack speed while containing critical strikes and critical damage. This way the output of the damage that will be done is significant.

Passive Focus - The longer you dont attack, the more chance on a critical strike you got.

Frost Shot - Your arrows will slow the enemy upon hit to not let the enemy get out of range

Volley - Shoot multiple Arrows down a in a wide cone in front of him damaging and slowing.

Hawkshot - Shooting a arrow that reveals a certain point on the map where you fire it, . and gives extra gold with killing minions and monsters.

Encahnted crystal Arrow - Stunning the 1st champ it hits and slowing the rest of the champs that are close by.

I have chosen for Flash to get out of hard situations where you cant survive. Or flash in to make sure the opponent dies with your freezing skill shot.

Pros

- has the ability to slow the enemy from running away. (CC)
- Its a ranged champ so you can stay at range of fights/teamfights
- Excellent farmer
- Good utility

Cons

- Item dependent
- Squizy
- Hard early game due to low health.

Get a good position on the battle field to gain maximum proficiency out of teamfights to help the team from runners - and the champs who needs to be focused as 1st.

Depending on the enemy in your laning fase get a good position so you can farm easily, Last hitting is suggested while moving behind your minion line. Depending on your 2nd champ in your lane you can play aggresive or defensive.
