I've got a lvl 30 DH and lvl 9 WD. I'm at the portal that leads to Act 4 with my DH and still in Act 1 with the WD, so i haven't opened the Nightmare difficulty yet. My question is, how do you guys level your characters? Do you go through the harder difficulties with your "main" until you get tired of them or do you finish up normal with new classes before taking your 1st character to 60? Or just jump between classes as you fel like it? I know there's probably no "right" way to go about it, but just curious to see how others are handling it. In my experieces you sort to have to get in a rhythm with a character to so jumping back in forth seems a like it would be a little wired for me.
