at 12-13 mins there shouldn't be any teamfights yet and you should get your bf sword, if you fail you suck at lasthitting

That means you sure can get one defensive item, if it increases your eventual damage output by living longer. See what I did there?

And there are many times where you need to b early because you got killed, ganked multiple times, etc etc. Those are good instances where you either get more doran's blades, or you get a pickaxe as early item toward IE. If the other team constantly ganks your lane, and denies you of exp, you have a harder time harassing enemy champions and csing. You need to maximize output, and generally what I end up with around 18 minutes is zerker boots + 2 doran's blades + BF sword (if I had easy farm) or pickaxe + another doran's.

You can even go zeal before finishing IE if you need movement speed. Or get catalyst if you have a really tough time in lane and your teammates suck at taking advantage of their respective situation.

Also, you don't use Ashe ulti primarily as a interrupt in a teamfight. You use it primarily as a long range engage to another lane (when your jungler is going to gank). 3 Second stuns to a ganked laner are far better than just waiting to use it in a teamfight and only doing little damage, short stun without securing a kill. An arrow across the map that connects with a teammate (or 2) close usually is a guaranteed kill. And even if a teamfight is about to happen, you can delay long enough with hawkshot, cv (vision of enemies delays teamfight, you can optimize positioning) to have your ult back up. It's a really short cooldown anyway.

i can just imagine the kind of person you are in a game lmao

"FUCK GUYS CALL MIA I HAVE NO MAP AWARENESS"
"WHY YOU ALL LET ME DIE"
"OVEREXTENDED? MORE LIKE HIGHER LEVEL THAN OTHER GUY FOR TWO SECONDS"

Assuming no one is ganking.. or even harassing. If you are sitting in your lane with no one to face, well... leave the custom game. Only a retard would sit there and let an Ashe farm uncontested. If you're bottom lane with a support, which you should be, the other side is going to be trying to poke you down.

lol berks? zeal alone is enough for attk speed and kiting mid game. nn pd unless the game is dragging and you have extra money.

IE+zerks+PD+LW is the core of Ashe. Items you will get in 90%+ of your games.

youre better off with mercs for cc reductions or swifts for better kiting/chasing. you shouldnt need attack speed.

You shouldn't need CC reduction, your team should be protecting you as Ashe. Swiftness has no use when you have PD+tier2 boots. Your damage (and your slow) mainly comes from autoattacks. You generally don't have lots of time to autoattack if the other team has good positioning, so everytime you have a window of time to poke and deal damage, it should be the highest amount you can.

assassins > ashe

Assassins usually can only burst down a single target before they go down. As Ashe you need to watch your positioning and stay behind your teammates, and only attack when you either can secure a kill on a high value target (an AP/AD carry), or when your positioning is good enough that your teammates can stun/CC an assassin so you can flash/ghost away. If you die as Ashe, most of the time it's your own fault because you get greedy. Proper idea then is to back off, but most of the time it's pretty hard to resist not going after a low hp champ
