I leveled Marauder, Gladiator and Pugilist to 6 for ability goodies, and I really like the ability to mix and match stuff. I've become a fan of Gladiator, which I had no intention of leveling but it is pretty fun. Rampart is a big help when you are getting your head handed to you, Bloodbath and Second Wind are awesome. So far my favorite job is Marauder, just something appealing about a little miq'ote swingin' a big axe. I also found myself sucked into leveling botanist and miner, which I didn't think I would like but gathering is strangely addicting.
