- They're "taking a close look" at clearcasting abilities. "One likely outcome" is changing them so they restore mana instead of making spells free to cast, which would still give you mana back, but would not kick you OO5SR.
- It has finally been spelled out that they balance around even 10-man raids having Replenishment. Although I think this is silly (why not just remove it from the game, if everyone should have it all the time), it makes me feel a bit better that they said they are "likely to offer this ability to additional classes" (it's already been announced for Destruction warlocks, for instance).
Overall, although this feels very "sky-is-falling," it's important to remember that Blizzard is not trying to make healers sad, or break the game, or ruin your class. As they spell out at the bottom of the post, this is for the purposes of giving encounter designers more room to play. If healers can't run out of mana, they only way to make the encounter hard for them is to throw huge amounts of raid damage around, which is not always the best choice for an encounter.
This will be going up on the PTR, of course, so we'll get a chance to see exactly how it plays out. But I know a certain Holy paladin who will probably want to stop completely avoiding gear with MP5 on it in the near future.
