windsong can proc 3 times, 1 time on MH 1 time on OH and 1 on abilities. It also has huge uptime so it quite often happens that I have 2 or 3 rolling at the same time. Havent tested elemental force yet but I can't imagine it in any way being better since its likely limited to a low ppm. It wont do more than 3-4% of your total damage if even, which the extra offstats from windsong definately top.
the once mainhand once offhand once abilities is not true for windsong (You're thinking landslide). with it on one weapon you can achieve all 3 procs (one for each mastery,haste, and crit). It procs on -everything- be it instant damage, DoT, magic, melee, heal.
Has anyone out there tried using EF/WS? I am thinking about trying it out.
Assuming your sims are 100% correct, I would still roll with Windsong/Windsong purely because you're not always going to be on your target. When you get a mastery or crit proc your dots will still tick when you aren't on your target while Elemental Force doesn't proc from poisons and bleeds. I do believe it procs on Venomous Wounds but...it's been a while since I last tested this. My point is, when you have to move away from your target for any reason (AKA dropping the fire debuff on Feng or resetting stacks on Elegon) Windsong is still going to give you a benefit while Elemental Force doesn't.
And let's be honest here, take a small look at the numbers. Elemental Force/Windsong in a 450 second patchwerk fight gives you a grand total of 59 more DPS. You only have to not attack your target for a fraction for Windsong/Windsong to edge ahead.
Same sort of situation for Combat Rogues in Dragon Soul with the haste proc trinket and Vial of Shadows. Vial of Shadows is always free damage while the haste proc can be wasted if it procs during the wrong time, a phase change, or you name it. Yes the haste trinket was simming higher, but it didn't always perform higher.
Whoops I should really answer the OP's question huh?
I would definitely run with Windsong on both weapons. The uptimes on the buffs are really good and will always give you a big benefit. Elemental Force will diminish in value the better your gear becomes. If you are still leveling and run with greens, get Elemental Force however.
I tried every combination besides Windsong/Elemental Force (did try it the other way around) in a raid setting and any iteration with Elemental Force was behind.
Bovan, Elemental Force does proc off DoTs now with the new proc model but Windsong is still better.
Oh crud you might be right actually. When exactly did they change how Elemental Force and Windsong worked in terms of procs? All my testing did come from before that blue post, although I'm still standing by my point that movement and non-Patchwerk fights make Windwong edge ahead.
Yea the testing I did was shortly after MoP's release. Or after Mogu'shan Vaults opened to be precise.
When that blue post was posted I was already using Dancing Steel so I didn't think too much of it. While I can't see my older results being wrong, I'll do some testing some time tomorrow after our raid to see if I still get the same results. Problem is, I can't actually test it in our raid this time.
I run with the agi enchant and windsong, i find windsong usualy has one of the 3 buffs running at all times so i dont think i will lreplace it any time soon, and the agi proc seems very nice. last time i checked with dual windsong you cant have more than 3 buffs even if you get more procs, so some of your procs get eaten up by a refresh which is why i rather windsong on 1 hand, not on 2. this way when somethign does proc i runs full duration and i dont eat buffs
Keep this in mind: The elemental force proc does not cleave for blade flurry for combat specced rogues, BUT cleaving DOES benefit from the extra crit/haste/mastery uptime from running double windsong.
I tested all 4 combinations in simulationcraft and for single target on a combat rogue, EF/WS was the lead combo by a very small margin over the other 3. The margin was maybe 1% dps across all 4. I personally run double windsong until I get dancing-steel-worthy weapons.
So in conclusion .... MH / OH = Windsong/Windsong or Windsong/EF ?
Honestly the best way to find out what's best for you is to run Simcraft with every combination. If you don't want to do that, I would stick with dual Windsong enchants until Dancing Steel (which will only get cheaper as it becomes more available).
