I just started non-ladder a couple weeks ago but I started with a hammerdin to get some super basic gear, then leveled a frozen orb sorc to do real mfing. I just can't stand leveling a sorc with absolutely no gear, you just die instantly to anything. So I got some basic sorc gear and now I'm reversing the roles and my sorc will find a bunch of gear for my pally.
Frozen orb sorc is solid because you can do quick andy and meph runs, chaos runs, and plenty of the level 85 areas. My go to right now is Andy-Meph-Chaos runs.
I'd love to throw Trav runs in there but they are still pretty annoying. I need to find some fire absorb items before I can do those efficiently.
