Upon hitting level 85 and playing through normal/heroic dungeons, I felt like I did as a DPS back in Burning Crusade: It was challenging. To me healing felt extremely rewarding and if the group failed, I could feel assured that it probably wasn't my error.
That said, looking back at raiding I'll have to say that I've had the most fun I've ever had in raiding so far. Some may not agree with this, and that's fine, but the Triage model (in a Paladin playstyle at the very least) really resonated with me positively. My problem with this raiding environment this whole expansion though, is how it felt that raiding mechanics have almost regressed.
Tier 11 was a pretty big tier, with the introduction of BH, ToT4W, BWD, and BoT, and so fights felt different every time. You went from some high movement fights to fights that had intricate mechanics (Still kinda like Omitron), and THEN you had fights like Chimaeron. Kinetic movement took priority over static in this tier.
In Tier 12 we started to see a pattern, however. Things started to become *Come over here, stack. Do stuff. Heal.* Some fights deviated from that, but from a healing perspective it didn't seem as varied as T11.
We get to T13, and while I genuinely enjoyed it - if I have to stack up any more for any fight past this tier I may just go insane. In T11/12 The stack-up and heal model was novel and fun. By T13, when we're facing the end boss, I didn't want to be on his back (or a platform) spamming Holy Radiance. I don't know what happened there, but It didn't seem too creative with the mechanics - and that makes Practical sad.
On a more positive note: Healing has been more balanced than it's ever been. There are some slight discrepancies, but I think that with the de-emphasis on absorbs (WoTLK), the difference between pure HPS healing and Proactive shielding really isn't so large because damage output isn't as crazy.
It's in my opinion that the quality of life changes made (such as judging for paladins) are great and I hope that you guys continue looking at how you can improve it all.
