Yep, you get a wide range of responses from people.

On a related note, I have several different multibox groups which have received widely variable responses:

4x Night Elf Hunters = 99% negative
4x Midget mages = 99% positive
1x dorf priest + 3x human locks = 50%
4x Undead priests = 75% positive
5x Undead (priest+locks) = 60% negative, but this was after warlocks became "OMG OP! NERF!"
1x BE pally + 4x UD mage = 50%

It is interesting to note that the trends appear to be much more influenced by the current consensus on how OP or not OP a particular class combination is, with blatant exception of night elf hunters in particular and hunters in general. I don't have any shammy or druid or other groups so can't comment on those, though I have a sneaking suspicion that they'd both be at 50% or leaning positive for druids and the opposite for shammies.
