A note on clerics, I wouldn't underestimate the easiness of playing one.
Lower levels it's fine, but as you get higher and higher you'll notice that you seriously have a lack of damage to solo your way through a level (unless you're built for pure solo XD / CS's)
So in order to level, you'll have to party. Fun and easy to get into one, harder to actually keep people alive especially if you lag etc. *O*
