[Bard of Prey]

I'm going to have to chime in on the 'forget diplomcy' side... partly because I've seen more strategy games ruined by poor diplomacy than I've seen improved by it, but also because I don't think it suits this game very well.

One huge problem with allowing you to move through your allies' territory in Dominions is this... what's to stop you from moving your Prophet and your Pretender all over your so-called ally's territory in order to subvert their dominion (or just sitting on their capitol for that matter)?

You could conceivably destroy a nation you supposedly had an alliance with this way... and while a human player would recognize what you were doing and break the alliance, how would a computer player tell the difference between this exploit and 'accidental' interference you might cause from just being nearby?
