First off heres my profile for frame of reference
When I'm deciding how to reforge My character I can't Look at a Set of Plots and say Oh If I add 100 haste I get 300 dps but If I add 100 Mastery I get 280 DPS.
When I decide to add 100 Haste, Im sacrificing something, I can sacrifice 50 INT or 100 Crit or 100 Mastery. Ive reforged all of my crit off to get to the 7060 Number Im at now, so now that Ive reforged all my crit off, where do I go next? Heres where My reforge Plots come in
Here's the latest reforge plots for my character, The Curve is still quite similar to the one I did a Month ago when I had drastically different gear
At 7060 Haste and 13246 Mastery Im doing 155964 DPS.
Heres what I get for 1000-5000 less and More haste instead of Mastery
2060 Haste 18246 Mastery-152329
3060 haste 17246 Mastery-153732
4060 Haste 16246 Mastery-154271
5060 Haste 15246 Mastery-155078
6060 Haste 14246 Mastery-155505
7060 Haste 13246 Mastery-155964
8060 Haste 12246 Mastery-156073
9060 Haste 11246 Mastery-156098
10060 Haste 10246 Mastery-156668
11060 Haste 9246 Mastery-156907
12060 Haste 8246 Mastery-157150
As you can see I am seeing steady DPS gains reforging into Haste all the way until I get to 7060 (the number has in fact moved up a little bit from before where a Month ago this was around 6050). The Difference in reforging from 2060 Haste 18246 Mastery to 7060 Haste 13246 Mastery is around a 2.33% PATCHWERK DPS gain. If I go the Full Monty and go alllllll the way up to 12060 Haste and 8246 Mastery, Im only looking at a Paltry .76% PATCHWERK DPS gain. Clearly at some point here, Haste has Lost some Value.
Now Youre just gonna have to trust me when I tell you that I have run reforge plots for many many characters the last month, and I have yet to see someone with the EoTE/EB Talents NOT have this smoothing out of the reforge plot curve at around the same area.
Here's where it gets complicated, I could Reforge off all of that Mastery and add more Haste and realize that .76% DPS gain, But is this Relevant to the current tier of raiding? Not Really! Theres 12 really Unique bosses this tier, and Most have some sort of Cleave or AoE component. The Problem with this is that Haste is By far Our worst stat in every situation where you are adding a Mob. The More you add, the worst Haste is, Let me show you the weights Im getting with 2 Mobs
Here's 3 Mobs
And 5 Targets
So as you can see, in ever situation where we add mobs, haste becomes by far our worst stat. So the Question for me when Im deciding my reforging is, Is it worth it to sacrifice .7% of my patchwerk DPS to realize a Decent gain elsewhere? For me, I like to play to what our strengths are. We are strong at AoE damage. to me .7% is a drop in a bucket and well worth sacrificing to be very strong at cleaving and AoE
So there ya go, I'm not advocating a simple cut and dry approach. If you want that Ill say go for Hit cap of course, then reforge to around 6-7k haste (use simcraft plots to see where your setup begins to flatten out), then if you care about your patchwerk DPS, stack more haste, Otherwise youll get better results on Cleave and AoE fights with Mastery.
Caveat, while Yes I have showed simcraft to favor crit over Mastery on 2-3-4 and 5 targets, I dont feel the tradeoff of Going Haste to 6-7k > Crit> Mastery is worth it, it would take a lot more work to figure it all out though
