If you run an noe mission that goes over water, and as you get there a hoard is waiting for you magically. Someone probably watched you from the CV just out of your visual range as your big red blob of dots passed by on their dar. POTW got caught with that twice in the last few months. The epic fail hurts but, the epic fun generated can't be complained about. At least we cornered a hoard of red guys where they were willing to shoot at us. It was our own hubris that we only brought TuTus because we were convinced we would have the base down and captured before the hoard showed up.
A lot of bad unexplained out comes against the best laid plans, are simple hubris and impatience over coming the planning. You only have so much time to spend playing, and the arena looses population at a know rate in the evening. So you want to get out there asap and have fun. Anyone who has been part of a mission noe over water where an enemy CV was never supposed to be, knows how it feels to be flying along cutting up on channel with your friends and 5 inchers open up. At least your mission accomplished finding a hidden CV.
