I've heard that shamans are a little weak both in the healing department and dps.
I've heard the same thing about Monks.
Which would you advise to someone for LFR/Normals, especially in terms of being fun to play?
MW Monk is the most fun I've had playing this game since Wrath. 3.0.2 Ret pally was the most fun but I digress. If you like melee dps the MW Monk is the way to go. If you like ranged dps a Shaman is an ok option.
I personally think the MW Monk is the only decent class in the game. Its the reason I resubscribed after being gone for over a year.
