Class Duo Suggestions

[superstar]

Hi, so I'm wondering if anyone would like to tell me about which two classes compliment each other in terms of leveling and efficiency and fun stuff...

If I have a friend that wants to play, what should we roll?

Ultimately it will come down to which ones we each just like the best, but I'd like to hear about any experiences or formulas others have with specific combos.

And in particular, what would go best with a bard?
