Picture it ... Wailing Caverns ... a hunter and a priest queue for a random and find themselves with a druid tank.  The panic begins ... is this one of "special" druids which thinks well as long as I have the spec, form doesn't matter.  The answer in this case was a resounding "Yes".  The "tank" was in all forms of leather gear ... boomkin spec'd... not a good sign. The most special aspect of this druid was the belief that tanking did not take place in bear form. No he was a caster form tank ... occasionally going into kitty for fun. Needless to say the group fell apart by the rapidly departing members of the group after seeing him run into the first boss and casting moonfire and poking him with a big stick.
