I'm bored... What should I level next?

I have one of every class leveled at least into the 80's with great gear on each. The new content drop rate is so bad I've gotten bored with it and want to level something else. What should I level?

Here are my current builds:

Fury Druid

Javazon

Poison Bone Necro

Gold Find Shout Barb

Cold Sorc

Fire Lock

Smiter

Mosaic-sin that was leveled Traps

What sounds fun for a fresh start? I don't typically enjoy ladder unless there is something worth grinding for a specific build
