Haste revisited!
With the nerf to Gift of the Earthmother in patch 3.3 the haste landscape has changed a bit. This post covers the changes to haste needed to achieve your much loved 1.0 second global cooldown again!
How does haste scale with your cast time?
Haste increases the speed you cast your spells (lowers the casttime) with and lowers your global cooldown (gcd). The global cooldown cannot be lowered under 1 second. However the lowering of your casttime is not limited. There is no such thing and a haste cap, you can have infinite haste untill your spell is instant, which is unreachable. Your haste stat can influenced by gear (including gems and enchants), talents or aura’s (buffs, elixirs, totems etc). The only talent that can lower your gcd or spellcast time through haste is Gift of the Earthmother and Celestial Focus. Another talent that lowers you casttime is Naturalist, but it only affects Healing Touch and not through haste.
Is haste a stat a druid should look at? Yes, but only when you feel you have other stats like Spellpower, Spirit, Intellect and MP5 are sorted.
Formula of haste
Haste_needed = Casttime/ (1+Casttime_wanted/100)
- haste_needed is the x% of cast speed increase
- casttime is the casttime of the spell
- 1% increased spell cast = 32,79 haste rating
- global cooldown is 1,5 seconds, which can be lowered to a minimum of 1 second.
Global Cooldown
The Global Cooldown (or gcd) is the time you have to wait in between spellcasts before you can cast another spell. Lowering the gcd would give you the ability to cast more spells in the same amount of time and thus more healing. If you use the formula above to calculate how much haste you need to lower the gcd to 1,0 second, you will need 50% increased speed or 1640 haste. It might be reachable, but at a huge cost of other attributes which are more important.
You can get the gcd of your instant healing spells down to 1 second. How? Through Gift of the Earthmother, Celestial Focus, possible raid buffs such as Moonkin Aura/Swift Retribution Aura (3% haste) and Wrath of Air Totem (5% haste) and haste from gear. How much haste does a druid need with or without these talents and buffs? These haste numbers will give you a gcd of 1 second on Rejuvenation and Wild Growth:
| Haste from gear needed to get a gcd of 1 second for Rejuvenation and Wild Growth | ||||
|---|---|---|---|---|
| Raid buff | Not talented | Gift of the Earthmother 5/5 | Celestial Focus 3/3 | Both Talents |
| None | 1640 / 50% | 1148 / 35% | 1497 / 45,63% | 1063 / 32,39% |
| Wrath of Air Totem (5%) | 1405 / 42,86% | 980 / 29,87% | 1269 / 38,70% | 856 / 26,09% |
| Moonkin Aura (3%) | 1497 / 45,63% | 1062 / 32,39% | 1358 / 41,39% | 936 / 28,54% |
| Both raid buffs | 1269 / 38,70% | 856 / 26,09% | 1137 / 34,66% | 735 / 22,42% |
As you might have noticed Gift of the Earthmother treats Lifebloom differently. For Lifebloom it gets 10% from total haste and 10% extra haste (so 20% total). This means you need less haste to get a gcd of 1 second for Lifebloom.

Haste and casttime
Haste increases the speed of your spellcast. A nice stack of haste gives your druid more spells to cast in the same amount of time. Which means more healing output. If you look at the formula you will see that the longer the casttime the easier it is to lower your casttime. This is because haste is based on a percentage and not on a absolute value. As you can imagine 5% of a 3 second Healing Touch cast is higher the 5% of the 1,5 second Nourish cast. This also means you need more haste to get the same absolute amount of your spellcast (0,1 sec of healing touch 3 sec cast means 114 haste, on the 1,5 nourish cast it means 234 haste).
Now tell me, you voted yes or no for Celestial Focus in the last poll, still sticking with your choice? I am curious!

I have celestial focus
After picking up a new necklace last night I’m now only 20 points off my haste cap while in a raid (with a boomkin & shamen) and I’m quite pleased with my choice. To get there I did have to also regem a few things… all my yellow sockets are now SP/Haste 
So far pleased with the choice… may change that if I end up naturally picking up a lot more haste, but I think CF is the best choice for now 
ArchDruid Angela´s last blog ..Happy New Year!
so i am kind of new to 25 man raid healing. but have reached a pinnacle were my icc25′s need a little more oomph. i am a little confused haste can lower my GCD to 1.0 from 1.5 which is great but it also lowers my cast time so how fast is it “practically” possible to cast a 3 sec healing touch? and surely the time saved there and other cast tiem spells is better than the .5 from the GCD which realistically only helps your instant cast rejuv lifebloom and swiftmend because the other spells encompass the GCD in thier cast time. so i guess i am asking how much time can i expect to cut off from my 3 sec healing touch i would like to make this a much more viable heal with a 3 sec cast there are jus too many better options.
Fill in the formula and you know what your casttime at a certain amount of haste will be.
Healing Touch (non-glyphed) is a no go (even with enough haste) compared to Nourish (1,5 sec cast and powerful) and Swiftmend (instant and powerful). Only way I use HT is with nature’s swiftness but still Nourish is better (unless there no HoTs on your target).
tyvm for the info i found it quite helpful. my nourish is at 1.13 cast time and ppl have described me as having machine gun heals lol
