All Shadowbringers did was staple the Storm's Eye extension to it.
And arguably people weren't wrong about pre-4.2 Warrior. You had to spend 2 minutes building up to your Inner Release+Berserk burst to get your big 6 Fell Cleaves, Upheaval and like 2 Onslaughts and any kind of downtime would throw a wrench into it, back when melees still had a lot more downtime and during a raid tier where the last boss reset aggro, forcing you to build up enmity again which completely threw off your expected Beast Gauge gain.
