Just because you're a specialist doesn't mean you're meant to push lanes, it just means you have the kit to do so. Sylvanas has really strong lane pushing kit with her W and Q. However, she can turn teamfights around with her silence ult and if you are good with your Q and build her right you can focus enemy heroes down fast. She can also solo camps (slowly). I usually top both hero and siege damage on her by knowing when you should push lanes and when you should kill heroes.
With reference to your build I use this build:
1. With the wind (that extra range really helps to get that killing blow)
4. Envenom (one of the best single shot abilities in the game)
7. Follow through (v good with the amount of times she hits an ability and her reasonable AA rate)
10. Wailing Arrow (Gamechanger in team fights)
13. Evasive fire (more manoeuvrability, which is everything in current game, gives you more push ability when enemy is fleeing and makes fleeing easier (just hold down Q))
16. Blood for blood (the other best single shot ability in the game)
20. Bolt of the storm (get this and you won't need double E, you can literally pop in and out of combat as you please, you become inuriatingly difficult to lock down)
With more reference to your actual abilities. Setting her up to kill heroes means you will get frequent recharges of your q, so ranger's ambush is useless, so I take envenom. Windrunner is nice but blood for blood is always going to be a better option. If it was in a different tier I would think about it. More useful if you don't really know what you're doing with her though. Combo of blood fo blood and envenom with 5 charges of Q and a shot of W = dead enemy hero.
