Now, fortunately for Josh and his girlfriend, we've actually been asked this question before, and anyways this sort of topic comes up lots and lots and lots of times in one way or another. I'm happy to refer them, and all interested parties of two, back to those posts with comments from our insightful readers. Of course if you feel something has changed since those topics last came up and there's a new best duo in the game, feel free to let us know here!
But in order to give this post some kind of interesting spin, how about we advice them what not to do! What would be the absolute worst class combination imaginable for two people to level with? It's not as easy as you think -- As our class encouragement breakfast topics have shown so far, each of the classes has their own form of face melting, ass-kicking uber pwnage, and they all seem to have abilities that complement each other, no matter who they're paired with. Still... there has to be a less-than-optimal combination in there somewhere, right?
Ideologically, you'd think that paladins and warlocks just would not mix at all, but no, that's not true! Actually they work great together. From my own experience, I remember practicing as a 2vs2 arena team with a mage friend, who is an excellent player, but we still didn't do very well at all. I know it could be just because I may be a terrible druid, or my gear may not be good enough, but it's actually the only time in this game that I've ever paired up with a friend only to feel that maybe our class abilities didn't complement each other well. I thought that if I could level my rogue to join her we might be a lot more successful, but my friend thought that I just needed more practice. Maybe there is no worst class duo! What's your experience?
[Check out the girlfriend's answer in the last panel of this great Penny Arcade comic above, and take it as a warning not to choose for your duo a new class that you like toooooo much, or else you might not be able to resist soloing with it when you have free time and your partner doesn't!]
