Battery  

So, I just dinged 90. This is kind of different than Assault. It is an upgrade to Assault, and on the same timer. But they changed it to where it isn't a proc now when you cast it like Assault, but a damaging melee attack. This basically makes it better in the sense that the damage is regular damage, and it isn't resisted or anything, and can still crit. It is however, a lower hit than Assault, but seems to has less aggro since it isn't a "Nuke" like Assault was, and Battery still gives you the DPS bonus afterwards. Just shedding some light on how it is different
