Killing Spree is one of those abilities that seems simple. It’s a major DPS cooldown for Combat. You want to line it up with damage-enhancing procs to squeeze out every last ounce of damage. In that vein, tons of Combat Rogue guides out there advise only using Killing Spree with Deep Insight. But is that really true?
Last raid I was chatting in our melee channel, and the topic of cooldowns came up. Vuez, our resident awesome-at-ALL-THE-THINGS Rogue, said something I’d never heard before: “Just use Killing Spree on cooldown.” Apparently, he saw Killars from <vodka> use Killing Spree as soon as it came up and adopted the mindset.
