Fire Mage Sim Question

[Cauterize4Procs]

So I have a question about fire mage sims... im sitting at 43% crit/20% haste/20% vers/15% mastery. This is an alt , so my gear is meh. I have two haste vers ring , one 910 one 945. Got a 910 relinquished crit mastery ring and shows as a 20k-30k dps loss depending on which ring I replace
i just dont get that, thought crit mast was my best stats >.>
im using simcraft 735-01, is there some other nightly build I should be using for fire mage ?

Fire Mage stats for single target are Crit>Haste right now. Thats why u have a dps loss i guess

Ignore anyone who gives a flat stat weight when talking about fire.

730-01 is out of date. You can sim at raidbots.com, which is generally up to date.
