I just made a new account to pose a question I ran into while raising my item level from 501 to 504. I'm normally a Fire mage but when I compared the simcraft results from my 501 item level/gear to the new 504 item level/gear, it was telling me that haste weight was actually better than my crit weight as a fire mage. For reference, my 501 item level/gear had my crit up to about 34% so I know I'm capable of running fire and I sim with patchwerk fights just to see the raw dps.
Anyway, plugging the new weights into ask mr robot and optimizing gave me roughly 27% haste and 23% crit. Is this right? I know simcraft doesn't take trinket procs into account so maybe that's the trick here and I'm testing both sets out currently, but supposing the haste weight is higher, should I just switch to frost or is haste actually better for me as fire?
