The notion that StM is just completely bad for the spec and needs to go away is a relatively new thing. During Alpha & Beta most of the loudest feedback was overly positive. StM was hailed as "the most interesting ranged caster ability ever." There were a handful of long posts expressing concerns that it wasn't balancable, but these got drowned out by the cries of "something new" and "not boring."
Moreover, I would say that most of the negative feedback about spriests in general seem to be spurring from this community specifically. I don't see similar thoughts being voiced on H2P for instance. The core voice over there is primarily, "We're fine, learn to play and practice harder. Get out of the class if it's too hard for you." Personally, I think there's a fairly large, but publicly silent group that feels this way about spriests. They (still) feel that StM is the best thing that ever happened to the game.
