I don't think you actually used it in IR. iirc, it was only used outside of IR so you wouldn't overcap because you did not fell cleave outside of IR.

You would use it in IR any time you didn't need to gap-close in the next 10 (originally 15) seconds. It was literally free damage after 4.2 (as opposed to siphoned away from other potencies in your kit as per the current design's "free" Onslaught damage) and was useful to spend as much Beast Gauge as possible during pre-4.2 IR.

You also absolutely could Fell Cleave outside of IR; Onslaught stopped being a potency gain (and it was slight even then) over Fell Cleave the moment you got Enhanced Infuriate. You just wanted to be sure reach pre-4.2 IR at 100 Beast Gauge, so Onslaught could help set that up.
