Except for the fact that warlock is the weakest pure dps for quite some time now? Some hybrids do better too.
It was not a spell that we were supposed to spam in blizzard's design. By nerfing SP they fixed a flaw in the design. Now inci is hitting harder than SP, just like blizz wanted it, so we are spamming it instead. Like we did whole WotLK. I really don't see where is the big problem.
It's not like all of our fillers were nerfed.
