The thing is that a dps rotation will exist to maximize damage with or without a resource management system. If the system exists, then the rotation will simply take that into account and alter the rotation.
The added benefit is simply a change in the rotation (which is basically nothing) and the added option to burst with the sacrafice of not being able to do anything down the road. The downside is that doing the rotation wrong not only yields a lower output but also creates a situation where the player is told they can't do anything (which is just stupid).
The combat system doesn't need an overall inhibitor on a rotation. Having designated abilities revolving around the resource can accomplish the same strategic value just the same and also make those abilities feel almost godlike when they can be utilized.
