Energy is your main damage resource, why would you ever want to intentionally lower it?
If there's a second target around, sure it would be. It's also be more effective DPS to pop it without cooldowns up. Anytime you can hit a second target, it's worth hitting Blade Flurry.
If you're asking about on single targets... no. Just... No.
Well my question was more without a second target. Let's say it's Magmaw's vulnerable phase.. does it do any better to scale your energy regen back a bit by turning on BF while you have everything else popped that would normally cap your energy?
