Squishy

From WoWWiki

A term, arguably derogatory in intent, used to describe any of the more fragile, cloth-armor wearing classes such as a Mage, Priest, or Warlock. This term is also occasionally used for Rogues, Druids (at least, druids NOT in Bear Form), and even in some cases, Fury Warriors and Clothadins.
