Build and Runes
Play aggressively in lane against her, because her Volley has a really long cooldown at earlier levels.
Ashe has no defensive skills, which means she is really easy to gank/focus in teamfights.
Taking cleanse might save your life against her ultimate.
Ashe is much more threatening with a kill-lane support than with a utilitarian one. Use counterpicks to minimize laning difficulty.
Don’t true to chase her because she is one of the best kiters in the game with her slow.She will kite you till death.And she has 600 range.
