People want a healer that doensnt have cast bars.
So they think if they ask for DNC/CHM healers, they wouldnt get cast bars.
(And little do they realize, if DNC was going to be a healer, it would have had a "Dance" bar, and CHM will have a "Mixing" bar. Both of which require standing still, and both are effected by swift cast.)

Just accept the fact we're just getting a reskinned WHM.
