SK's and Paladins, because of certain offensive spells, have a much easier time snapping and holding aggro than Warriors, but people who say Warriors are useless are doin it wrong.

Edit: oh but to answer the OP question, yes, groups are plentiful everywhere. The only place I have had difficulty with getting a group as any class is on the Qeynos side of the world, just because people flock to EC and Oasis for lowbie xp like the crowding sheep they are. /who all crushbone, /who all oasis, /who all souldunga and the like are invaluable in finding people to play with!
