Don't worry, you'll get better if you try. Prince isn't too far away from Warlord, and I bet you could put up a good fight on it once you get up to noble. That is, if you want the cost of everyone blaming you for loss of victory
I'd invite you, hell I don't care if you're bad. Although, I'm thinking about going Monarch or Emperor on the next game, even though that may be above my level. Thus, it might not be very fun for you. But, keep your eyes open, we might even stoop down to Noble one of these days...
