Bishop - If you want a support role and semi-decent farming, but not great damage, great afk mule to level.
Beast Tamer - Same as bishop if you go kitty-meow-meow-form and just be XP Mule. Can also do Damage role too, pretty good, but much like aran gets boring real quick imo.
Mercedes - Great for Link Skill... Pretty much it.
Wild Hunter - Great for mobbing and mobility. Damage is nice. Not my cup-o-tea, but eh. Lots of them around because they are so good at the moment, until Evan Revamp where they pretty much become dirt.
