1. This sounds like an issue of perception to me. I know it happens, but with a lot of problems people complain about, I think it's a matter of thinking it a problem, so one only perceives it when it happens and ignores the other fights.
2. Similar to grizz's point, this is the MA, don't assume everyone is going to play your way. Heck, I hate it when someone chases our bombers 100 miles into friendly territory just to try and get a vulch on landing, I think that's lame, but it happens, we deal with it and continue to have fun.
