Well, maybe here's one reason, from early in the thread (quoting Lusted):

Whilst the overall balance for each of the Kingdoms campaigns is the same, there are differences between each campaign for game-play reasons.
Search the post for more info. That makes sense... sort of... if you consider each Kingdoms campaign a standalone mini-game. But I still think it's a terrible decision, if it means you have to change your tactical thinking for the same units when moving back and forth between Kingdoms campains, or the original Grand Campaign, because the units are balanced differently. That really makes no sense to me, but then I didn't design this game.
