Before I begin, I would like to clarify that this is not a "which class is better" thread.
So I'm currently running a rogue for DPS, but I'd like a dedicated healer as well. I've got the choice of: 80 paladin (never liked paladin healing), 80 priest (which I've started gearing as disc spec) or 26 druid (which I'm considering levelling to 80 and speccing resto with). Leaving out my paladin, this gives me the choice of choosing my priest or my druid.
I enjoy healing as disc but the idea of needing a whole seperate spec/set of gear to be able to raid heal as well really irritates me. I like a druid's ability to be able to focus heals or spread them out as needed, which a disc priest really struggles (by design) to do. I also don't like the idea of potentially clashing with caster DPS on gear rolls (surely not every piece of disc gear has MP5?), where a resto druid doesn't have to compete as much since there is only one other leather caster. On the other hand, I've already got four 80s, and the thought of dragging myself through Azeroth+Outland+Northrend for a 5th time really doesn't appeal to me.
So my question is: Do the pros of having a versatile raid+tank healer that has less gear competition than a priest outweigh the cons of having to level yet another character? Or can the priest community give me some reasons to stick with it instead of going bush?
I'd like your views.
