Just wondering if anyone has done any theorycrafting on spell haste rating and where it will fit in with item budgeting. From the items I've seen so far, a good deal of caster items found in Black Temple have spell haste rating on them, but I personally only see the benefit for dps casters. Items like
Bracers of Renewed Life lead me to believe Blizzard thinks spell haste will be good enough for healers to sacrifice mp/5 for.
Will spell haste be primarily a situational stat for healers, switching it in when quicker heals are appropriate? Or will a faster heal allow for enough regen time to sacrifice mp/5 for?
On paper, I personally think spell haste, as a healer, doesn't seem attractive enough to give up mp/5 and +healing for.
On the caster dps side of things, how attractive is spell haste for mages and warlocks?
The PTR notes mention that the haste rating was nerfed to provide less benefit per rating point, but I haven't found any actual data regarding how the formula was changed.
