Eh, don't worry about shammy CC. It counts as a polymorph mechanic with dispell flag of curse. Druid, mage AND resto shamans can dispell it. If you are going up against any team that has a druid in it, don't even bother with it at all, if you cast it on the druid he'll shapeshift out of it, if you cast it on somebody else the druid will dispell it.
Course you won't care about the above unless you PVP
Still though, it'll be fun giving shamans every bit as much hell as I give mages.
