Rework Ashe! pls read before comment

after playing a few ADC champions and comparing them to Ashe, I have the feeling that Ashe is only good if your team is willing to put in the effort to get her there. that being said, almost every ADC needs assistance in lane, it's why they get the support. Ashe however, I believe, requires more attention and work to carry her. when her late game comes up as well, she only seems good for her slows and ult. it is with this thought that I propose the changes I do with some knowledge of the games lore in mind. I will answer questions asked.

Ashe The Warmother of Freljord P:Avarosa Reincarnated Ashe's basic attacks cause a slow that stacks the more auto attacks she lands on champions. The slowing effects stack with items you build.

Q: TrueIce's power cost: 50Mana Range:800 Ashe can call upon the magic of Avarosa's bow. Ashe builds up Focus by attacking monster, minions and champions. While her Focus builds, Ashe becomes more accurate with her attack. Upon activating the ability, Ashe's range increases (600/650/700/750/800) for 5 seconds.

W: Biting Volley Cost: 50 Mana Range:1000 Ashe fires 12 arrows in a cone causing increased damage. These arrows can be blocked by minions and monsters. Fires arrows in a cone, each dealing {{ totaldamage }} physical damage. Enemy champions hit by one of the arrows gains the brittle for {{ brittleduration }} seconds. The next immobilizing effect against a Brittle enemy has its duration increased by 30% and deals {{ brittlepercentmaxhpcalc }} of their max health as magic damage.

E: Warmother's Escape Ashe can dash in a direction and leave a small surprise. Ashe can dash away, leaving a small snow trap at the start and end of her dash. If an enemy champion walks over the trap they become slowed and gain the brittle condition. If the champion is already has brittle then they become stunned.

R: Crystal Ice Arrow Cost: 100 Mana Range:25000 Ashe fires a missile of ice in a straight line. If the arrow collides with an enemy Champion, it deals damage and slows all enemy Champions. Launches a crystal arrow of ice that hurts the first enemy Champion hit, dealing {{ rmaindamage }} physical damage and slowing surrounding enemy Champions. If enemy Champion that was hit has Brittle, they are knocked back and surrounding Enemy champions gain Brittle on top of being slowed.
