WAR Beast Gauge = New Rotation?

Fellow Warriors, how has the Beast Gauge changed your play? The gauge fills faster with Storm's Path, so that's been featuring in my rotation far more often, but I'm not whether I should be burning a Fell Cleave as soon as it's up or stacking two of them (plus Infuriate for 3).

How has the Beast Gauge changed your rhythm of play? Any early theorycrafting thoughts?
