Im loving SK, started dominating from the mid game on in most of my games on him, but I'm having issues in lane, I can't seem to win my lane no matter what. Some are even lanes that I can survive until I get blink and then roam elsewhere with ult, but others are horrific lanes where I feed every time I come close to the wave, where it seems like they always have sentries and have better attack animations/damage than me so I can't get caustic finale off. How should I lane on this hero? Is there something im missing?

Also, what to get level 1? I get burrowstrike usually but if I'm not contesting the bounty it feels weird to get it since I most likely won't be using it level 1. When is it better to get sandstorm/caustic?
