The problem with Ashe is that she doesn't have excessive attack power. She's super item dependent and in a lane where you can't farm (when you're lane-mate is constantly roaming and you're against two champs who can freely harass with no fear of counter-attack, as was Mal's case) then you really bring very little to your team other than initiation. Granted, initiation isn't a bad thing to bring, but when you do virtually no damage, you can easily bait your team into starting a fight that's really bad for them.

Tristana is actually my recommendation for learning to play ranged. Because her Q is such a massive steroid, you can go into a fight with only a couple damage items and still do a lot. Her rocket jump/ult combo does insane damage when you're in-lane, making it pretty easy to snag a free kill here or there. She's also just incredibly safe (try ganking someone who can blink two screens and knock you back a third).

Graves is a good one for pretty much all the same reasons Trist is. Even without farm he has a steroid and very substantial burst. His passive is also complete bullshit, making it really easy to trade damage with an opponent profitably.

Sivir's another pretty good one, with her ult as a steroid, easy harass on the Q and AA reset for extra deeps on her W. Spell Shield isn't remotely as safe as Tristana, but it's still more than Ashe has.
