Overview: The usual Kill Skills build with a bit of survivability thrown in there, this also has less of a focus on movement speed creating your dmg multipliers and more on combining the dmg from movement and shooting through the barrier.
Usage: If you are used to the speed builds with Zane, this build will be more dificult to adapt to, but once you do it is hard to rely on movement speed multipliers again. Essentially pop both Action Skills prior to a fight, and start killing as many people you can while running around with your barrier. Most cases; everyone is dead before your skills end. BUT for those times where you need to wait for skills to come back, we got increased cooldown and some ways to mitigate Kill skill downtime (taper your Action Skill activation - i.e. activate one then just as one ends, activate the other)
Playstyle: Less focus on movement due to the added barrier dmg bonus, but combine the movement bonus with the barrier and you get a ton of dmg! So i'd say, stationary barrier when you know that movement isn't neccessary, then pick up the barrier for mobbing/run n gun for combined dmg multipliers from movement and barrier (mitigates the dmg loss from picking up barrier).
Action Skill choice: I feel you have a choice, but i think the build works best with low cooldown type Action skills due to the reliance on Kill Skill activation so i went with both drone and barrier, but you can swap Clone with Drone if you want, but you NEED the barrier.
