But in the Campaign, I much prefer to have some really strong and easy to play factions (ahhh, the Vikings!!!) for those days when you just want to kill things, and some really weak, hard to play factions for when you are looking for a serious challenge. I think RTW has done that really well.
I completely agree with this statement. Balance is for multi-play.. single play is about what type of game you want. Easy, middling, or tough as nails?
