Beastlords, duos and multiboxing

Flaming_MMO

I am more than likely going to start out a new beastlord soon (just waiting on a deal for the AoD expansion) and usually box my characters, to me it just makes things more engaging since the game is pretty easy leveling up (especially nowadays, with mercs).  My question is what other class goes good with a Beastlord?

  I was thinking an inquisitor or a dirge, but am open to pretty much any class suggestion, I would prefer a FTP class if possible (Yes I know a dirge is not FTP)
