Wow, I just simmed my character and haste is way better for DPS than any other secondary (excluding BA). I had no idea. I suck apparently. Or SimC does. Or both.
I also was under the impression that Multi was way ahead of the others; apparently it's 0.02 normalised ahead of mastery. Oops. Maybe I should just go for mastery since the dps loss isn't worth the ridiculous survivability loss.
Is haste actually that good for damage done? But I might start dying if I don't get all my delicious multistrike health.
Edit - ah but of course I only have about 2% haste and 40% multi. I'll sim someone who isn't going for multi and see what it says for them.
