This week, we'll mix up the Co-Op Classics formula just a bit. It has certainly been a huge news week, particularly today with the announcement of another class, the Wizard, in Diablo III. Much as the original announcement of the game did this past summer, this got me to thinking about the original Diablo games. Obviously, co-op was a huge factor in the success of these games. So which class combinations are the most effective? I'll give you my take on a combo from Diablo 2, and we'd love to hear from the Co-Optimus community as well. Which class combinations do you feel are the best?
