Dude the base GCD is 1.5 sec, not 2sec. That means you need 33.33333% haste which is 523.333333 spell haste rating.


Anyway, I came here to question how you can fix a dmg equivalent to something that itself doesn't increase your damage. For a class that simply spam a spell, like destro locks or mages or ele shamans, yes spell haste gives a direct dmg increase. But as a shadowpriest, unless you get enough spell haste to actually fit more mind flays into your rotation, spell haste won't do shit.

wrong. you need 50% haste. you are confusing casting speed and haste. seriously, look for some other posts on haste theory. or even wow wiki.

Here's the correct way of calculating it:


To get a 1.5 second spell to 1 second:

New Casting Time = Base Casting Time / (1 + (Spell Haste Rating/1570)).

1 = 1.5/(1 + (x/1570)) <=> x = 785.

And also wrong about your other statement, but I really don't wanna start into it again. Look for yourself in the thousand of other topics.

Haste and +dmg

So I was thinking about this - would a weapon/oh/wand swap macro be the best way utilize both haste and +dmg?

Set your SWP/VT spells to

/eqiup Orb of the Soul-Eater
/cast Shadow Word: Pain(Rank 10)

Set MF/MB/SWD to

/equip Heart of the Pit or Fetish of the Primal Gods
/cast Mindflay (MB, SWD)

It's a minor point, but it would put the most +dmg on the dots, and the spells affected by haste would benefit from haste.

you are right except weapon swapping gives a 1 second delay in spell casting which would defeat the purpose.

Bleh, didn't test it first, lesson learned

Thanks.

Just wanted to thank the TE for this great post.
I was faszinated howmany people were suddenly interested in haste with 2.4 going live - and NONE of them read the discussions going on here since the 1st day of the PTRs.... just another horrible example for human stupidity.
Thanks TE for solving this - at least i hope so ^^

You can make the weapon swap directly after a spell is cast which will effectively use the GCD as the weapon swap timer as well.

I can't believe how many people are arguing. The OP is there to tell you this is how it is. Not open debate on why he's wrong. This has been discussed for MONTHS.

As far as the weapon swap... while its an interesting concept, there'd have to be a significant difference to make it worth the effort. Lets look at it:

Main hand: Most likely you have Hammer of Judgment. The haste weapon you're likely to replace it with is Reign of Misery, if not the Sunflare. Both of these have more pure spell damage than the Reign, so we wouldn't swap it anyway. If you have the staff from Illidan, and were gonna swap in the Hammer, you could gain 28 damage.

Off hand: Heart of the Pit being changed for the Orb would net you 12 spell damage. Unless you're swapping out the Illidan staff, in which case its already built into the 28 from above.

Wand: Swapping the Demonsoul for the Stick would gain you 2 spell damage, assuming you gem the Demonsoul with the haste/spell damage.

So for most of us with the Hyjal hammer, you're looking at a gain of 14 spell damage. And it would demand you cast in a certain order, because you'd need to put the weapon swap at the end of a spell, so you'd need to know what spell was next. Doesn't sound worth it to me.

Im am flabbergasted at how many people open up the same counter-argument to the topic creater.

When the creator has basically said "i am making this so all the questions that silly people are about to ask can be laughed at"

Its the same questions over and over, hell even i made the mistake of "33% haste = 1s GCD no?" at some point im sure of it.

Only thing i would add to your original post is that formula nasta posted so everyone can see what it is as well as adding the spell haste wiki link to your post as i found that extremeley helpful in explaining the simple difference between "spell haste %" and "casting speed".

Nice work.

Quick question; I'm trying to get enough spellhaste gear to get in the so-called sweet spot (160-180 spellhaste) and I picked up http://www.wowhead.com/?item=34697. Now, with a +8 spellhaste gem in it I would activate the socket bonus so that would bring the pseudodamage up to 10, compared to a normal runed living ruby's 9. I'm at 14xx dmg raid buffed.

Seems pretty obvious to go for the spellhaste gem but everyone says don't gem for haste, so just wanted some opinions on this specific item

hm basicaly thanks for a very informative post. *nodnod*

Praeme id gem yellow or orange, the haste variants. Not Runed Living ruby. Due to the socket bonus.

True, a http://www.wowhead.com/?item=35316 would give me one extra pseudospelldmg. Cheers

Ever since being directed to this site by a fellow SP (thank you), I have used the Best raiding and casual gear threads as gear-check references. I want to say that I appreciate this site and the posts as a valuable resource.

I have been following the various spell haste threads up to this point. Frankly the theorycrafting leaves me a little boggled.

As a shadow priest with just a little over 1020 damage currently, I have been unsure of whether to start stacking haste over damage with the new options available to me. Frankly, it doesn't seem to make sense until after 1200 damage and approaching the "assuming 1400 damage" (not sure I'll ever see that) that the theorycrafting always refers to.

I found this post to be helpful in my choices.
Thank you.

Just want to thank all of you who have worked (I imagine) very hard on all these calculations in regards to haste and damage.
I've been a raiding Spriest for a little over a year now and having hit 1493 spell dam with raid buffs I started to get curious about haste. I see that I am a bit late in all the discussion and I am in a general sense very behind on the mechanics or in's and out's of a shadow priest. That being said I consider myself a pretty good player and I am excited to start to learn more about the little tweaks I can make to my gear to boost that ever present dps factor.
So thanks again. I thought you guys would like to know that some of us do greatly benefit from the work you have done and that we appreciate it greatly.
I was tempted to ask whether it was worth me beggining my haste venture with the only two piece I have (waistwrap inf. and fetish) but I chose to read.
What I learned is that sure I could start with those two and lose 30 or so plus damage while gaining 3% haste but I think, from what I have read, that I should wait until I get the ring of ancient knowledge (probably next week if it drops) and maybe even the t6 bracers until I replace the orb and cord.
The point is, I think, that there really is no right answer. These gear guidelines are suggestions and aren't mandatory.
So thanks one last time. I am looking forward to playing around with my gear instead of just hunting for more +damage I can now finally look for something else to benefit my spriest.
