Since my previous thread was closed and I was not able to get an answer, i thought I'd post the information I was ABOUT to post on my previous thread:
-------------------------------
Ok so lets start a time line.
Two seperate warriors, identical gear, identical rolls behind the scene, starting with 30 rage:
1 = Imp Heroic Strike
2 = Imp Slam
1: 30 rage initially. At 2.9 seconds: 18 rage (30 - 12) Damage: (351-421) +157
2: 30 rage initially. At 2.9 seconds: 38 rage (30 + 8) Damage: (351-421)
1: At 3.4 seconds: 12 rage (still) Damage: 0
2: At 3.4 seconds: 23 rage (38 - 15) Damage: (351-421) +87
Another Heroic Strike and Slam
1: At 5.8 seconds: 6 rage (18 - 12) Damage: (351-421) +157
2: At 5.8 seconds: 23 rage (still) Damage: 0
1: At 6.3 seconds: 6 rage (still) Damage: 0
2: At 6.3 seconds: 31 rage (23 + 8) Damage: (351-421)
1: At 6.8 seconds: 6 rage (still) Damage: 0
2: At 6.8 seconds: 16 rage (31 - 15) Damage: (351-421) +87
So within 6.8 seconds, you'd get a total damage from Heroic Strikes of (702-842) +314. You'd get a total damage from white hit + slam of (1404-1684) +174. If you take theoretical worse case scenario and best case scenario, the Slam still comes out ahead.
***now this is assuming no offhand hits (impossible), no crits, no weapon procs, and unbelievable (and unachievable) timing. These are theoretical values to show the number crunching. This does not calculate in other abilities. This is pure Heroic Strike vs Slam.
But again, you may say "Well you proved to yourself that slam is better.." I have not. I need help thinking about how it effects the offhand, and if that effect counters the benefit of using Slam. Please post reasoning behind your decision if you post and not just "Slam's reset timer would make Heroic Strike better."
-------------------------------------
Now after reading this thread I do agree and disagree with some points made here. As of last patch, Slam is not interuptable. If you dont "slam spam" you'll be able to get the offhand hits in, but the question is, how much will the .5 seconds offset the rage generation from the offhand hits?
According to
http://www.wowwiki.com/Formulas:Rage_generation my Thunderfury in the offhand will do approximatly 3-4 rage per hit. I really am not sure how to speculate the lost rage due to using slam.
Yes, you do have to have good timing. But the added benefit of using the slam vs heroic strike is the same as using WW over HS whenever the cooldown on WW is up... the extra hit for crits and proc rates. In the example above (even though it's false as there's no way to time it that perfectly,) example 1 hits 2 times in that 6.8 seconds whereas example 2 hits 4 times. That's 4 times to proc flurry and any weapon procs/enchants you have (granted 4 times to give crusader 1 chance to proc.)
Again, it's all theory. I understand it was tested with a 2h build, but why not try it on a DW build. The intent here is to increase the # of hits per minute and save rage to use for other instant attack abilities. You can say that you dont have enough rage to use this ability, but I have found myself the rage even when keeping Rampage up and using WW and BT as soon as they are available. I stay in Berserker Stance and pop Bloodrage and Improved Berserker Rage whenever they are up (keeping battle shout up as well.)
The entire reason I started thinking about this is because I've been a prot tank for the longest of times. I recently (2 or 3 weeks ago) had some people educate me on why using Whirldwind over Heroic Strike was better (for the purpose of getting more attacks in to increase DPS through flurry and what not.) When I tested this out, my DPS improved dramaticaly. Anyways, take a bit to actually read this if you would and understand what i'm trying to bring up. I know it's been sort of discussed, but I'd like some more thought on this matter.
Thank you, and I apreciateyour time. :)
