Top Berserker builds maintain permanent Berserking not by chasing a proc, but by structuring the entire rotation so a Berserking-refreshing skill is always coming off cooldown before the buff can expire, using weapon-swap mechanics as the connective tissue between skills.
A documented rotation: Steel Grasp to pull/debuff, Double Swing (dual-wield) to refresh Berserking, Death Blow (2H Mace) for burst, Iron Maelstrom to clear the screen - with weapon swapping between these acting as the engine, since each swap also reduces the build's Ultimate cooldown by roughly 2 seconds.
Berserking's uptime is not a random proc in this design, it is a deterministic consequence of never leaving a gap between refresh-capable skill casts; the weapon-swap-driven Ultimate CDR is a bonus side effect of the same rotation rather than a separate system to manage.
Roughly 2 seconds of Ultimate cooldown reduction per weapon swap in the documented rotation.
Build the skill bar and swap timing around never having an idle window longer than Berserking's own duration, rather than relying on a single 'refresh' skill in isolation.
