While I agree that they perhaps increased bribery costs to much, I do prefer it as it currently is to how it was before. As it is now, bribery is something I try only when I've done an 'oops' (i.e. Ack, a full stack army is at the gates and I can't get an relieving army there soon enough!) Bribery is an expensive, very very expensive, solution. But definately not something that I'd use simply to remove an annoying enemy force that could be defeated by one of my armies.
