Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
So you've chosen Ashe. What a pro.
Use this build setup and NEVER STOP MOVING unless you know theres no champion near you.
If your suspicious of a gank, use Hawkshot whenever you can.
Use Volley to Harass and slow.
Use the arrow like a hero xD
NOTE: from the 5-10 minute mark, DONT BE A HERO. This is when this build is at its low point. After that you will become the godmode ranged DPS.
But really this build doesnt need explaining because its just so good. Try it out. My average K/D with this build is 10:1 lately.
