A fun set-up for a 3-4 player group?

[fugazi]

I played an SK on live and my best-friend-and-neighbour played a bard. That was a non-traditional duo that worked pretty well.

Iksar monk/warrior/shaman seems like a decent set-up, but a halfling warrior/rogue/cleric (or druid) or a dwarven paladin/rogue/cleric set-up would also work. The bard pretty much makes any other duo function better, so you could always replace the rogue with a bard and then slap on a druid instead of a cleric since the bard adds some healing/buffing power.

I think both of them will want to play casters though, but I rather have them try out a shaman or druid over the mage or necro.
