When I first checked out the official PTR change list for the upcoming patch 4.3, I wasn't expecting many holy paladin changes. We've been performing admirably in Cataclysm, comfortably straddling the line between obsolescence and ubiquity. Upon the reading the changes, I was shocked to see such radical changes to our talents, spells, and playstyle. Patch notes like these are always scary, as we don't know if we're being gutted or reinforced. I immediately downloaded the latest PTR client and got to work.
Holy Radiance was completely retooled into a cast spell that we use on a friendly group member, with talents changed to reflect the new design. We gained two new holy power sources, and Light of Dawn had its target count shifted. Our bread-and-butter mana regeneration mechanic, the Seal of Insight and Judgement system, was also scrapped in favor of a flat regeneration buff that scales with our spirit.
