I generally play support (some times offlane) and my go to hero when I see a SS is Lion. Soon as I hit level 2/3 and have stun and hex I'm off to smoke gank mid lane. And rather lately after watching ti5 I've become very good at adapting with wards, so there's that to always help for incoming ganks / information.
Communicated with my bloodseeker (friend irl who i was palying with). I hex, he silences I wait the full duration and then stun and finger if I have too. Rinse repeat.
This is how I dealt with storm spirit in my last game.
