I would make free migration to 3rd and weaker kingdoms in power. This would make it harder to drop cities for short window of time and allowing flood of migration coming only to retake cities fast and dominate.
I am dueling a lot. Sometimes people ask me why I had 100% heal if it was neutral territory. It turns out that this is what my opponent saw. The truth was I lost units because my battle report was different than my opponent.
same issue here. Me and my friends have the same problem. A week ago we had 2-3 potions when finishing ruins quest. Today I have 2-3 out of 10 ruins quests. !!! Energy is so scarce that I don't login very often nowadays.
