I have been Holy Priest until dinged 80 when i changed to Shadow and stayed that way for a long, long time. My secondary spec is Discipline PVP but since i haven't played PVP in a while and i don't think i am planing to I've considered changing it to a holy or disci spec. My new guild doesn't have a healing priest which is another reason i should respec. I have 0 healing gear but i have 203 triumph and 123 conquest emblems.
Since i cannot remember and i couldn't find any reasonable source of what should i aim for when starting i am asking if someone can guide me through what stats should i aim for at the beginning and what will be most important later in 3.3. Also i would like to know what roll would be the most valuable for me to perform, and which spec. We have a shammy and a druid healers. I've basically experienced both but i would like to know what would be most valuable to the current situation.
Thanks in advance.
