Question for any ele shaman

Hey, on simcraft for my shaman it rated haste wayyyyy more beneficial to me than mastery. I thought this was false because on the interwebs everyone is saying haste is = to mastery.
The exact stat weights were 1.5646 for haste and 1.1887 for mastery. Even in a 5 man i noticed my dps seemed to lack a bit ,but ive never raided on my shaman so i dont know if the sim was correct or false.
