Last year, Nethaera, a Blizzard community manager, informed us that the interaction between Protector of the Innocent and Beacon of Light was completely intentional. Holy paladins were still feeling out the new spells and talents that we received in Cataclysm, so it was nice to know that at least one thing was working as intended. Now, some ten months later, we're seeing Beacon of Light and Protector of the Innocent disconnected from each other on the patch 4.3 PTR. Why break a mechanic that's worked right since its inception?
The developers aren't happy with healers in PVP situations. The massive Holy Radiance changes were a nerf to PVP holy paladins, and the PotI nerf affects them more than raid healers. The devs are also buffing Mortal Strike effects to allow them to cut our healing down by 25%, up from the 10% healing debuff that we've been working with for months. The Seal of Insight/Judgement changes also affect us negatively in PVP environments. Removing Holy Radiance from our Speed of Light talent reduces holy's mobility.
