Sorry, I don't have a premium account, so I have to respond here. I'm up for a truce. Otherwise, we're both doomed.
Leaving the south alone would be helpful. It would be helpful if you could consolidate your troops in the South by taking the red continent (Caerleon, etc) and the orange (Black Castle, etc). Otherwise, you could just attack red (who is actually a friend of mine, but he still needs to be crushed).
