I personally do not like to respec and I play my priest mainly for one reason, end game raid healing. I do not PvP. Up until that point, I wanted to make a build that allows me to be a viable healer in 5man runs until 80, but at the same time does not gimp my questing and grinding capabilities... in short, a hybrid build until I hit 80. To this end I thought of the following lolsmite build until I hit 80.
You will note that this build is missing 10 points. That is because up until this point (the point I will be at when WotLK comes out, I am fairly certain that this is how I want to place my skills. The next two points I would put into Enlightenment while the next three would go into reflective shield.
That leaves me with 5 points to spend on I have no idea what. Both rapture and spiritual healing can greatly increase my healing performance. Rapture can let me heal for longer and even grinding, gives me some mana back when my shield is hit. Spiritual healing is just the win since it makes me 10% better at healing, but gives me almost no benefits in questing and grinding.
What I like most about this build is that it seems like it would be pretty decent at both healing and DPS while at the same time, can benefit greatly from all the plus spell crit gear that is normally not as useful to a priest as other classes (The change to surge of light is very welcome since now both healing and smiting benefit from crits not to mention good old inspiration). I also like this build since I think the new WotLK end of tree talents are fairly... lackluster... while the changes to earlier parts of the discipline tree are very nice.
Any constructive comments on what you like in this build and what you would change are more than appreciated, "this build sucks you newb" comments are not.
