[Werlop]

Bards are much loved for pulls/crowd control, and everyone needs a cleric. As CC or Cleric, it's usually easier to get a group than it is as interchangable_dps_class#2. Mages are solid but there are a million of them, and druids are mostly meh at the endgame (although, like with any class, a great druid is amazingly handy).
But mainly, you should roll what you want to roll. There's no point in rolling a bard because they have an easy time getting into Seb groups, only to get bored before you ever see the inside of Seb. If you play your class long enough to get a solid reputation, that adds more to how desired you are than your class alone.
