Shoudl be interesting.
Even if they don't hit a city itself their stacks should be very large. Large enough to safely make moves in Spulla territory I would think and get access to resources to burn. Spulla wouldn't be able to divert too many units to hit a raiding stack without weakening their city defenses too much at least at the start it looks like. And with the other teams working on construction and in near future being able to bring down some catapults Spulla will probably need to turn the war in their favor earlier rather than later. Once they start losing their improvements and having to pump out units their ability to research is going to disappear pretty quickly. If they lose their strategic resources and the others are determined to stay at it until their gone then they're going to be hard pressed to win if they don't take out something significant at the start and to keep their resources and improvements intact.
