I'm personally leveling up MCH that way I can switch interchangeably between BRD/MCH. Keep in mind that if you do level BRD/MCH once you get to the real ''endgame'' content, you'll really only have to get one set of gear since the two classes both wear any ''... of aiming'' gear. So the second my MCH hits 60 I'll be able to slap on all of my 220+ gear from my BRD (save the bow of course) and jump straight from whatever ilvl I happen to be at once I hit 60 to roughly 220+
