Basically Ashe is a cheap, but very strong Attack Damage Carry (ADC) that does great on 3v3 and 5v5. She does great damage, has good slows, and a Hawkshot ability showing surrounding areas. Playing Ashe you are going to want to Have all of your Items, Abilities, Masteries, ect. to all lead to good Attack damage, speed, and life steal essentially making your champion "OP". Overall Ashe is a great and cheap ADC who is fun and easy to play, if you haven't you should definitely try her out.
