Boxboy,
I see you are in Tucson. Maybe it is an Arizona thing. I am down in Sierra Vista. Last night I flew in the MA for the first time since the change and saw a bunch of "wierdness". No discos fortunately, but had someone comment to me about "nice warp" and saw some warps. I shot a YAK point blank with a K4, had parts slam into my plane (thought I collided) and then the YAK just didn't exist anymore. No kill credit, no falling plane, no explosion, it just ceased to exist as if it had never been there.
My other Tucson based Arizona squaddie and I could not agree on our DAR. He would see my DAR counter over A10 and be looking to join up with me, I was flying over A53.
So I echo your comments. I can't explain WHY.. only that it IS. And these are issues that didn't exist prior to the change.
