Huh, you're right. This makes tristana a much better auto-attacker than jinx, at least for the most important 7 seconds of a fight, and she has much longer range while doing it to boot. Why do I see all these pros play jinx in tourmanents, instead of tristana, then? I don't play adc much, as I suck at it, but it seems to me like tristana should be a great one, with her terrain-traversing jump that resets on kill/assist (seems superior to jinx' passive), and her ult that knocks people out of her face.
I guess jinx does have her fishbones, but when she whips that out her attack speed drops to almost nothing.
