Does anybody have him ranked, and or knows a good rotation for him?
Build to sp2 before hitting overdrive (use heavy to remove some battery if required) -> sp2 armour break -> overdrive -> keep pausing overdrive with sp1s (most fights will be over in this rotation)
I would say he doesn't have a set rotation, you can just do whatever to stay in control of the fight, though the rotation that @YsF mentioned is the best in terms of damage. Build to sp2 before hitting overdrive (use heavy to remove some battery if required) -> sp2 armour break -> overdrive -> keep pausing overdrive with sp1s (most fights will be over in this rotation)
