Curse of Darkness was given a 3-second internal cooldown to combat an exploit involving Bard song spam which was causing performance issues. This has obviously crippled the ability, and on Varsoon it arguably isn't worth casting anymore beyond the initial pull. For instance, On a large encounter-based fight on Varsoon, Curse of Darkness made up 8% of my damage before the nerf. Now it's 1% - an absolutely massive nerf. Varsoon's also a very different environment than Live though. With a much smaller kit a slow cast/reuse, squeezing every drop out of Curse of Darkness is pretty critical to doing good DPS. What's the nerf's impact over on Live?
