As such, you're getting a 300 potency attack but removing the 11% bonus from either a 280 or 270 potency attack, which is either an 11 potency loss (280 / .9 = 311.11) or breaking exactly even (270 / .9 = 300). You're actually losing slightly more than that because you're slowing down your next Inner Beast by 1 GCD as well, but that's harder to directly calculate.
