Lich King has been a very stressful time for me as a healer. I sincerely think that it was the worst time since the beginning of the game for all healers. The reason is relatively simple, mana was nearly infinite as soon as you got your first epics. The developpers had to provide us with a challenge and as mana management wasn't one anymore, they enforced more damage spikes into the game.
Before this last expension damage was more controlled, a tank wasn't going to die in a 2s interval and none was going to die in one shot if not at full hp. People were dying when the healers were out of mana, not before, unless they made major blunders.
Wrath of the Lich King changed that and unless you're not doing what you should (and I mean by that doing content according to your gear level which means for most of us doing ICC hard mode considering how was most people gear before the launch of Cataclysm), you surely got this stressful feeling that even 1s of lag can turn your tank into a dead man and your raid to wipe.
I don't like this stress, this mandatory super fast reactive play in response to spiky strong damage. And I was having a lot of hopes for Cataclysm to bring back the "old style" when thinking was more effective than spamming and you had time to chose the right heal for the right time instead of pressing your strongest and fastest heal button as fast as you could.
It seems that it is the direction we're going to, and I'm happy of that. But Holy Paladins changed a lot too with the introduction of patch 4.0 and further. We lost a lot of our core abilities (Judgement heal, Holy Shield, Holy shield hot, several benedictions and others). We gained Holy Power and our new rotation style of play. It is fun and a lot of change from before and it surely makes the Holy paladin a very unique experience to play compared to other healers.
But sadly I don't like it.
What I want is for my choices to matter and not only for my talent spec. A rotation play is fixed, the best way to play is already written, follow your rotation, any diverging is a loss. My view on our new playstyle is that your only choice is who you heal, and even for that there is optimum and sub-optimum. I could be a bit reductive and paint it darker than it is, but that's what I feel. I don't really think that this concept of Holy Power allows for managing your mana by making the right choices, it is just a tool to allow you by using Word of Glory to duplicate very differently what paladins have always done since the beginning: being power batteries that run out after everyone else to keep up the tank as long as possible. Before we were using mana feedbacks with tools like Illumination, now were are using free heals obtained through Holy Power.
Even though it is fun to play, I like to think. So I'm going to leave my paladin behind, even if still fondly attached to her and her frostwyrm. I'm going to start Cataclysm as a Resto shaman, as I already wrote about before.
I'll still be a healer, and I'll continue to post about healing in instances, and later raids, but I will not provide specific paladins inputs anymore as I don't like to talk without facts. I'm sorry for my fellow paladins that like the blog, I promise I'll try to give you general healing inputs that can be of use to you as any other healer, like the Heling Through series that will hopefuly continue into Cataclysm.
I wish you all good times into Cataclysm, and as always, have fun. I hope to see you here again soon. And congratulations for surviving this deadly wall of text attack.
