You can use [Power Drift] or [Cunning Drift] or [Primed Sure Footed] instead of [Preparation]. I personally love [Preparation] because you benefit a lot from it in [Sanctuary], as your energy gets reset every time you enter the next zone.
Also, you could switch [Primed Continuity] for [Adaptation] and put some Duration Archon Shards in your [Volt] to compensate, if you wanna use this build in steelpath survival missions or so.
[Precision Intensify] can be traded for [Blind Rage] so your Pillage also benefits from the ability strength but at cost of energy efficiency.
Arcane Steadfast or Energize can be traded for Molt Augmented for more damage, but as you strip enemies of their armor, this should be enough for [Sanctuary].

As for the playstyle, you know it. Press 4, press 1, press 4, press 1, press 4, press 1 and so on.
