I was thinking to take off my dying curse to apply my Prism of Inner Calm that I got back in BC on Lady Vashj. It's a set number of threat reduced from crit strikes, and I wouldn't miss the hit from dying curse (and the proc could only happen a max of like 4 times, kinda sounds like a decent sacrifice to me if it works). It used to be amazing back in BC situationally. I could seed spam in Hyjal to my heart's content with it.
