Its not on the GCD. As a Troll, I have two non-GCD haste spells (Lifeblood and Berserking). I never used them at ALL so I just put them in macros on my two longer-cast spells.
#showtooltip Entangling Roots
/cast Lifeblood
/cast Berserking(Racial)
/cast Entangling Roots
#showtooltip Nourish
/cast Lifeblood
/cast Berserking(Racial)
/cast Nourish
if they're not on cooldown, they'll get popped.
there's an argument that goes like "oh, don't do that, use a modifier so you can choose when to use them...that way they'll be ready for those clutch moments"...but for me it's just a case of convenience (I don't need them for PvE; and I always seem to need them for PvP, otherwise I wouldn't be casting them).
This lowers Entangling Roots to 1.39 secs from 1.7 secs.
This lowers Nourish to 2.45 secs from 3 secs.
...not much, but better than not using them.
Edit: and now that I look at the numbers, it doesn't make too terribly much sense...Berserking is supposed to be 20% so, stacked with Lifeblood, the cast times should be shorter....I'm getting the numbers from the tooltip readings with both procs up. hmmmm.
editedit: as a warrior, you might just want to stick it in a macro with whatever you usually use as an opener. that way at least you'll get frequent use out of it.
editeditedit: the above doesn't consider the HoT, which I haven't tested, but looks like to be about 4% of total health...i suppose i could stuff that in a macro with my healing pots or something. hmmm.
