Hmm you are right. KD SA and my old UW BA. Prob is when i get a second KD relic.. What will you end up using KD SA + KD BA? Or damage proc (if we even have one. i havent checked the vendor yet).
I've extensively tested KD + UW and KD + CQ and I've found that KD and UW cannot activate together, even if they don't share the same cooldown. Whilst one is active, the other one cannot proc. While the CQ gives less power in general, the number of times it procs is much higher.
