Or you can actually show them the math and demonstrate to your raid how much they gain as a whole from people delaying cooldowns and ring uses and how much more of a burst execute ring explosions provide. These rings are a really powerful tool if you plan out their uses ahead of time. Of course, most people without complete knowledge of all the classes/specs and all aspects of the encounters are going to basically just make sure it's up for lust and use it on cooldown outside of that.
