Onslaught charge and needing rage

[P4X0R10N]

30s CD, but can be "rushed" after 15s' cooling at a cost of 1 rage per second rushed. Damage is reduced proportionately (50% at 15s) regardless.

Actually I'd really love that were possible.

Or they could make it 30 secs, 50 potency and add a trait that causes fell cleave or in to reduce onslaughts cooldown by X secs. Maybe like 1 or 1.5 sec cooldown decrease per fell cleave or inner beast would be nice.
