take out cleric stance will be a major error, the dps of the healer are not that interesting in terms of gameplay, for the whm it's place wind and do earth, earth, earth , earth ,earth... extremely funny, cleric stance it's there for offer a challenge to the healer in them rotation. you must pay attention to your tank and make sure you are good before switch in dps.
one important point, every healer have skill that heal in urgency even under cleric stance. i feel the healer need to train more them skill, i don't ask my healer to dps or point him if he don't dps. (im tank or monk) i only point my healer when i die, because i don't receive healing for too long. (what can happend rarely). the cleric stance swapping is skill, it recquire the healer to understand the limit of the tank and his own limit of healing. paying attention to a lot more than simply spam stuff.
take out cleric stance is a dangerous move, since it will give a free pass for teh healer to not try to become better at them jobs. some will not even try (the one that don't dps at all, that them right after all) and some try hard to become excellent healer that will use cleric stance, they do error and i will not judge them if they recognize when they have misjudge a situation.
instead to point to cleric stance, they need to enhance the experience of healer for some... that are quite simple.... to simple.... really really too simple.
ps: i don't talk of the raid part, i don't do sadistic mode... but in dungeon and primal they are not that hard to play in comparaison of some jobs that can be extremely tiring.
