I main Bard, but I'm planning on getting Machinist to 60 as well, because I love the gear sharing between the 2.

I've also got a lvl60 Scholar/Summoner and Dark Knight, but I stopped gearing them after I got them their ilvl200 eso gear, as it's too hard to manage for me (also, I don't like tanking/healing the current endgame content).
