Not to mention every Druid has Cower (though they have to be in Cat and melee range to use it) and every Shaman should have Wind Shear, unless that's been removed since I last played mine (pre-MoP). Technically the only "hybrid" I can think of that doesn't have some sort of "threat-altering ability" (since some people are getting bitchy about the words "threat dump") is Warriors.
