Been looking through the forums and don't seem to have found anything about this. I'm mainly going to be playing my campaigns as 1 vs 1. Should be picking the game up around Christmas time and as usual when I play things like this like to look into things first and try and work out some tactics/places to start.
What successful 2 character synergies are there?
Is there any combos that just don't work at all?
Any other restrictions I need to think about?
