I do have a question however... with haste if you have 30% taken off of a 2.8 sec wep vs a 1.6 or so would the haste benefit the slower wep more because in theory ( i dont know how the full mechanic of the game works ) just from looking at it... .84 sec would be taken off the 2.8 vs .48 on the 1.6.
but at the same time i think i'm over thinking it because the game is based on a weapon DPS rating...
Hi... I'm tired and its 1 am.
The percentage of increase you'll see in your white damage through haste is the same no matter what your weapon speed is.
The (mathematical) proof:
You can calculate your weapon's white DPS with this equation: ((min damage + max damage)/2) / (weapon speed/(1+((haste rating/100)/32.79)))) which can be simplified into (3279 + haste rating)(min damage + max damage)/(6558*weapon speed)
Now, you can just try it with different numbers. That's the simplest way to check. We can take the Angry Dread and the Hailstorm, for example. Two weapons with nearly the same DPS, but different weapon speeds.
Angry Dread's dps with 300 haste rating:
(3279 + 300)(274 + 509)/(6558*2.50) = 170.928 dps
Hailstorm's dps with 300 haste rating:
(3270 + 300)(164 + 306)/(6558*1.50) = 170.57 dps
So, as you can see, the increase in the weapon's white DPS is the same even if the weapon speeds are different. The 0.358 difference in DPS comes from the fact that Hailstorm's and Angry Dread's DPS values are not *exactly* the same. But they're close enough.
If you wanted to, you could also plot (3279 + haste rating)(164 + 306)/(6558 * 1.5) and (3279 + haste rating)(274 + 509)/(6558 * 2.50). Doing so would reveal that they're nearly identical.
Ugh, I'm bored.
EDIT: Didn't feel like double posting so I edited this post.
So, since I had some spare time, I decided to give the variant I mentioned (
0/23/48 [wowwiki.com]) a try on the PTR. I still lacked the glyphs, because I wasn't online when the glyph vendor was on the PTR yesterday evening, and respeccing made me lose all of my glyphs (what's up with that?).
Anyhow, I think that this spec actually outdoes the first spec I posted, the one with rime. The harder hitting ITs are just worth more damage than the +15% crit you get from rime. Although I had to play around with the rotation a bit.. Turns out trying to keep GF up 24/7 and using it in the second part of the rotation is a DPS loss. But not using it was a DPS loss as well, so my compromise was..
PS, IT, BS/BB, [UB], IT, GF, BS/BB, [DC], PS, IT, IT, [DC], IT, IT, [DC dump]
This guarantees 24/7 desecration uptime and around ~65% ghoul frenzy uptime. I'm sure that with enough haste or during bloodlusts and haste buffs of such nature, a death knight running this spec could fit the second ghoul frenzy in without losing DPS-- in fact, he would be gaining DPS if he can shave off enough time from the global cooldowns.
Anyway, test results.. I managed to break 3k dps multiple times with this spec and rotation and my gear level.
