Wouldn't an untrustworthy duke be good for you guys? Don't you all have Danellis anyways?
personnally i like to see all tribes become good. if a tribe is rubbish then were is the challenge.
you can't say your the best because you've defeated 50 rubbish tribes.
if i go to war(which i no doubt will) i will fight to the best of my ability and hope my opponant is doing the same. win or lose i might not become the best player in everyone else's eyes but i'll know i did my best against a worthy adversary.
that was the points of the middle ages and that is how i''l play this middle aged browser game.
