Yeah, it seems like they're trying to make MP management more of a personal issue, as well as making Ranged support less of a "must have" job for raid groups. They took away Manashift from casters, too.
The real test will be if they've designed battles and mana usage on healers to support that idea.
Depending on how much mana people (especially healers) come back with after being raised, I can see us getting Refresh and Manashift back in 5.1 if we make enough noise.
