Is there a break point where it would be better to reforge to haste due to legendary metagem procs instead of mastery? Or could someone explain to me how to sim different reforges (low on gold or I would just test it myself)? Right now I'm sitting on 22.5% mastery and 8.91% haste, and assuming my math wasn't wrong and that the proc rate of the metagem scales linearly with haste increases, it seems like if I reforged to 10% haste and went down to 21.4% master, I would have a pretty substantial increase in dps. I took the proc rates from one of my world of logs for metagem damage %, enrage uptime, etc. and then tested the change in haste and mastery % with a base 1,000,000 damage and got this.
Here is the log I took the %'s from
For the math I did I just assumed that the total damage for an encounter excluding the metagem and the benefits of mastery during enrage was 1,000,000
32.7% enrage uptime
94.3% of damage benefits from enrage
5.7% from meta
22.5% mastery
8.93% haste
6.38% from meta
21.38% mastery
10% haste
1000000 base damage
w/ 10% haste
1,068,670 physical
100000 nature
1000000 base damage
w/ 8.9% haste
1,071,940 physical
57000 nature
I wasn't sure how to take into account the fact that mastery also gives you extra melee swings, but it seems like the increase in the metagem procs would yield better dps than the increased mastery, especially in between full mastery %'s due to the rounding of Mastery: Unshackled Fury
Edit: I simmed it with a few reforges to haste instead of mastery and despite a 5% increase in haste the dps from the metagem only increased by .1%, so it appears to not scale linearly with haste at all.
