Mana is supposed to matter for healers

These hotfixes were intentional and we wanted to share more information about the "why" for you all here:

Mana is supposed to matter for healers, and in the case of Holy paladins, that just wasn’t happening. We were seeing raid groups attempting to learn new bosses where the other healers were out of mana while the paladins were still at 90% of mana. We also thought the acheter wow po experience of paladins healing harder heroic dungeons was inconsistent with that of other healers, or our design intent. We thought it was only a matter of time before groups started going out of their way to stack paladins for raids or recruit them for dungeon runs, which of course is not our intent. For this reason, we thought it was important to address this point now rather than sitting on it until a future patch.
