I hear ya...
This expansion just doesn't seem as tight in the 'rules' department as other releases, at least to me.
And nor should it be.
Unlike all of the other expansions, which have to accommodate x number of unknown people coming together to play, the Campaign is specifically for like minded individuals to operate in a group environment for a repeat amount of games.
Or, in a different set of terms.
Tournaments introduce you to new people and players
A Campaign makes players friends, if they were not already.
So it doesn't have to be as tight, because you are expected to work things out. As friends.
If you're not friendly, if you're not willing to sit down and talk - why are you expecting to get through x number of campaign turns?
You can't choose who you play at a tournament.
But you can who you play in a campaign with.
