No they don't. I said that was a small oversight yet it was still approved by the event creator so basically, not a problem from that line onwards.
All it takes is a bit of organisation to fight off bombers. They succeeded so apparently they were just better than you were at the time. As Evo also said, there is no reason why XA- can't intervene when Cortez is within their ZoI.
It is indeed a thread for feedback on the event but I don't see much feedback on the event; it's feedback (and 90% of it being criticism) being thrown directly at XA-.
