Holy paladins are doing all right. While patch 4.1's notes may have retribution and protection up in arms about the new cooldown on Word of Glory, holy paladins are exempt via Walk in the Light. We're actually not seeing any changes in the upcoming patch -- at least, none that have been announced yet. The lack of updates shouldn't come as a surprise to a healing class that's been performing relatively well. Minor balances to our mana and effectiveness have been used to keep us in line with the other healers, but we're otherwise stable. Patch 4.1 will buff our recently discussed set bonus, but that doesn't help improve the gear today.
Just because Blizzard doesn't have any buffs planned doesn't mean that we can't work on improving our performance naturally. There is truly no WoW player who can perform perfectly at every moment, but the closer we get to that ideal, the stronger healers we become. As healers, we should constantly be developing our skills and refining our gameplay. There's nothing worse than feeling like the weak link on the chain, and so keeping ourselves at top healing efficiency is crucial to being successful in whatever environment you're healing in.
