heck - I have a mage and a shammy... hex is NOT true CC. I think it fills a different role - and does it great! Sheeping (or 'makin the bacon') takes a mob and puts it to the side until you decide to deal with it later (especially with focus macros). Hex is closer in operation to fear or cheap shot - temporarily keep the mob from hurting anyone. The one minute cooldown keeps it from being a lockdown like polymorph - I agree with the above comment that the primary purpose of it will be to hex the initial kill of a set of mobs (usually skull) - burn him down, then keep the hex ready once it comes off of cooldown to freeze up any mobs that go after the healer - so the tank has 10 secs to regain aggro (pretty easy as the mob can't continue to beat on the healer - forcing the healer to heal themselves)

I do think that the heal component should be removed from polymorph - but have the 1st damaging attack not cause any damage. That way it's protected from the poly/nuke/poly/nuke cycle that justified the healing in the 1st place...

I was kind of hoping that shammies would also receive a CC over elementals (control earth elemental totem, etc...) - a 2nd class to cc elementals would be good, but hex has a lore history with shamans - so it's cool w/ me...
