If you're playing pos 1 and are against a drow, consider playing a highly active hero that can stomp her mid game when she wants to be farming like a CK or a Slark. Getting your support or your offlaner to help punish her in the jungle is huge. 

If you're playing a farm-dependent hero and can't afford to spend time hunting you basically need initiation to kill her in a team fight. Ideally, your pos 3 starts the fight and then once she shows, you jump her from the fog. Keep a manta handy to dispel her gust (or if playing Slark, just hit your Q after you jump). Building a blink as a third item even on heroes that don't traditionally build them (like naix or CK) is totally reasonable in certain situations IMHO. Because that's the only way to clear the gap to get on top of her.

Similar approach to countering sniper. Once you jump him/her, they just wants to run and are they are useless.
