This is a fantastic build. I'm thrilled to see people finally using tazer rounds. My build is similar to yours. I tend to go for envenom for a tier 2 pick just because for some reason I feel like I melt the enemy player more with it. Or, maybe it's that feeling when you know the enemy player thinks they are free and clear then suddenly they're killed, completely unaware that I poisoned them (I have gotten many lol's with it). Rather than advanced cloaking, I generally take lethal decoy because it applies pinning shot. It's excellent if you need to setup for easy mode snipe. Finally, at 20, I think I'm going to try rewind so that I can cc for days on the pinning shot + crippling. What are your thoughts on envenom, lethal decoy, and rewind?
