All too often I see threads about the unfairness of field aid. I think instead of slamming the concept, we come together as a group and discuss how we combat it. Before I begin, I will set some ground rules.

All posts with “I hate field aid” or the like will be flagged. That is unproductive to discussion and creates a negative atmosphere.

What is your tactics for wars with field aid? Do you go in with the same war team every time or do you make changes based on the type of war you are fighting.
