It's a very strange class if you play it as your main. You get tells out of no where from people you've never met acting like your best friend for a favor, people get mad at you if you don't do what they ask you(not everyone), you lose money on dots that people rarely compensate you for, and if you dare to take charge of a group then your a whiny lil brat hehe. I can't say the same about any other class except the chanter, but the cleric is what gives the group a greater edge.
The cleric is there to keep you alive, you don't like what the cleric has to say, then you just might die. I think the cleric has the best perspective of how your group is going to do and how difficult it will be to accomplish a goal from the very first fight.
For example, a group does a ldon high risk, the first fight goes very well and he/she doesn't have to cast a heal. I can tell now that my group can take on more than 1 enemy at time. I know we'll have a very good chance of success from the very first fight.
But let's say the first fight doesn't go very well and the cleric has to heal members other than the tank and the tank needs a cheal. This is going to go bad and somethings got to give. The cleric knows this from the very beginning, and should be listened to if he/she has any advice.(Switch tanks, allow the tank to draw more aggro before fighting, don't nuke so early, whatever)
Just thought I'd make a post about it, not being whiny =)
