As you get higher ilvl with more haste/mastery, SA starts falling behind other trinkets.
It's probably BiS if you are under ~850 ilvl, but once you get above ~870/875, it moves towards the middle of the pack, because those extra procs it's generating just aren't as relevant when you are getting enough procs without it; I'd expect it to be garbage after ~900 ilvl with high haste/mastery.
