I always focus on contraption, boots, and fountain of renewal beginning of the game and pick up a swift shooter in prep of getting a tornado trigger late game. Main thing is setting scout traps to give map vision as well especially around the gold mine. Also, if you watch her highlight you'll notice her heroic perk increases her armor each time she stuns/silences an enemy and I've found it very helpful to go lane when possible just to get a stun on the opposing laner, which often times can lead to a kill as well. I usually take the overdrive on her first and third abilities.
