http://www.icy-veins.com/combat-rogu...owns-abilitiesBloodlust (along with its siblings) increases our energy regeneration during its duration, which is actually pretty important. Without Bloodlust bolstering our energy regeneration, it would normally only increase our white damage done, which can be pretty low depending on our spec. Letting BL affect our energy regeneration ensures that all three rogue specs see a DPS boost similar to what casters experience.

Unlike for Assassination Rogues, Energy pooling is not beneficial for Combat Rogues. There are many situations when you will generate more Energy than you can spend (haste trinket procs, Bloodlust, Heroism, Time Warp, Adrenaline Rush, etc.), and you should spam your buttons even harder than usually during such times.
