I agree that these tactics of "jumping" and using vacation mode to protect treasures are an unintended exploit of the Travian rules. The rules need to be adjusted as many people have suggested:
1. All troops are lost during village relocation.
2. Kings/dukes cannot use vacation mode.
Although using these tactics is technically not any violation of current rules, I don't think it is an honorable way to play. The leaders of DOOM have discussed using these strategies in great detail and have decided it's better to play with honor. Our treasuries will always be available to attack and our hammers will never magically appear at your border. This may put us at a disadvantage, but we think it is the right decision.
