Blizzard has their head up their ass on that mana nerf. Anyway, it could make Spirit much more important because you'll have to compensate for some pretty high increases to your manacost.
Your heals will be around 15 to 20% more expensive to cast. So you need around 15% more regen to compensate for that.
