This is just a warning, while your post led to what seems to be some constructive conversation about priest mana management, the post you made on its own seemed somewhat of a whine. Perhaps (assuming talking about mana management was what you intended) you could put a question directly at that point near the end of your post. Something like "How are the rest of you managing to keep up with X?" Just a thought to help you not get posts reported, etc. Thanks.
What do you all think about actual priest mana regen? It seems to me that we are severely undertuned compared to the other healing classes. I mean there aren't too many fights where I run into mana issues even with alot of my gear having no spirit on it but I still find it quite annoying that paladins can almost mathematically never run out of mana, shamans can spam their powerful chain heal practically non-stop without a problem and druids can keep hot's constantly on every single raid member, effectively sniping most of the raid-wide aoe damage.
Priests seem to be the only healing class that actually can't faceroll and need to sometimes slow down a bit. On the twins 25hc for example, in order to compete with shamans and their 10-11k HPS I sometimes need 2 innervates which is kind of embarassing.
Don't get me wrong I'm not suggesting all other classes are overpowered and need a nerf I just think priests could use a tune up to be on par with the others in that aspect.
