It doesn't take skill to fight a horde. You fly through firering your guns pinging a few on each pass. Then you run like crazy waiting for them to auger in while trying to dive bomb. No skill required, just a bit of luck.
This past Saturday, I did exactly what you describe. I had upped a 190D to investigate a red dot showing on the radar. Never found the guy, so returned to base. As I arrived back at my field I noticed an incoming horde of P38s. I was considerably higher then them, so I was able to dive through the cloud of 38s several times, pinging as many as I could.
When they started their bomb runs, I scored 6 kills as they followed their bombs into the ground and augured.
I don't understand why anyone finds that to be fun.
I especially don't understand why the guys who can actually fly and fight, find any enjoyment in flying with the horde. If they were capping and vulching, then we would know that it is about scoring as many kills as possible. But the way they drop hangars and roll over the bases, the horde scores very very few actual kills. I just don't get it.
