Why do you people pick ashe??

If you want to make the choices for them, maybe this is the wrong game for you.

i'm better with her than those other champs (except ez because i just avoid playing him)

No champion is so underwhelming that they turn the game into a 4v5 - not ever. Bad players? absolutely. Your grossly overstating your initial point.

That being said, Ashe is in a rough spot - mobility is becoming a bigger and bigger deal, newer more assassiny mids and junglers are making it harder to play the 'safe adc farmer that snowballs' ... So as of right now? she's not in a good spot in the meta.

If you want my honest opinion? right now Support Ashe is more viable than ADC ashe - she has amazing CS recovery tools for mid/late game and her ult can straight up win teamfights. (It's still the best reason to bring an Ashe to a game) Build one of the gp5 items and go pure damage with your runes and masteries and buy an early Brutalizer to help you stay somewhat relevant. use her harass to absolutely win the lane (and she totally does, its hilarious to see the enemy duo try to figure out how to deal with it)

If you can make it through midgame using her ult and get some farm going, your late game becomes nuts as they struggle to focus down two adcs.
