This is the character line up I would most enjoy playing. It's simple, and everyone, (I hope), is familiar with the chars:
Amazon
Assassin
Barbarian
Druid
Necromancer
Paladin
Sorceress
So we have the original D2 cast. But let's add a few new chars...
Cleric- I like the idea of a priest-type char, with similar pally abilites and converts. IMHO, it should be a female char, cause there's enough men already. And honestly, your dying necro would appriciate the beautiful medic coming to save his life

Monk- martial arts master of the staff. Sorc/sin hybrid. He could use actual disciplines, like... and this is just random... the Bojutsu style.
Mage (or Sorcerer, but that's unimaginative)- like the Lut Gholein mercenaries. A perfect balance of magic and melee combat.
Rogue- as from the original Diablo. I liked her ability of being able to sense traps, and I think she should lean a bit toward the role of "thief", like from Darkstone (if anyone's ever played that. Real lame game btw that tried to rip off Diablo.)
So that's just my idea of characters. No crazy "good or evil" guys, and Blizz wouldn't have to bust their asses trying to create complicated chars that no one else could figure out how to play.
