Fair enough, I was wrong about him not being a pro level mid hero.
We can safely assume though that Technomancer is not playing against DK.Burning solomid, and that the advice I'm giving is still pretty legit.
I still think if you're good at holding the creep equilibrium in your favour then the highground advantage should allow you to ignore his harass somewhat and your higher base damage + runes should mean you win the lasthitting battle. He's also very susceptible to ganks in higher level games if he has to walk into the river.
Time to ask for advice myself: How to beat heroes such as sniper/gyrocopter with their ridiculous attack animations as SF? They have base attack damage on par with mine, but a way better animation. I find it really hard to get any lasthits in the first few waves and it snowballs against me from there.
force situations where you have to trade cs for cs. IE, get 2 creeps at low hp, and take whichever one they don't go for. Remember, they have good attack animations, but they don't have the attack speed yet to steal both cs from under your nose (Unless its flak cannon, but lel)
SF honestly just has to sit tight til 2-3, and raze for cs against those heroes, or any hero that has superior laning right off the bat (qop, ta, od, lots of heroes). Your best bet to take on a superior lane opponent is to call for a lvl 3 gank, as SF's nuke potential is stupid high at those early levels, and they probably won't suspect it if you're losing or playing defensive in lane.
