Besides adding extra dps going crane stance lets you pool mana tea since you generate and spend much more chi unlike serpent stance. its eminence healing isnt shabby either (touch of death ftw) unlike disc priests and i actually like the crane stance concept.
but yeah it's really subjective. personally i enjoy the spec, they have very interesting niches like stellar movement and powerful aoe healing. some will agree and some will not; imo theyre very different from other healers.
