One small whale and a few friends in one alliance kept under control by stronger whales. 2-3 players in that alliance seem to pick a target alliance, and attack gathering sites and weak cities once per week. One strong alliance controls everything they touch, so only the top 3 or 4 alliances can control facilities. Not a bad destination for a strong F2P player, or an active alliance. Player and Alliance name changes are relatively common. One player from the troubling alliance has a history of stealing 1 or 2 of the fortress and stronghold's first capture rewards.
