Hang!
I know what you mean!! I logged on last night, flew one time and logged off! Even though I had a great sortie, something was missing. It was the something that had me flying for hours on end. I am a much better AH pilot than I was before. I can hold my own pretty well but there is something missing.
Furious, I do the same thing. I will sit there in the tower for about 10-15 miinutes deciding what to do.
I have already sat in the tower, looked at the roster, read the text buffer and then just logged off, without flying. I do this more and more as time goes on.
It may be a squad thing. As of now JG2 only has 3 active members and I do enjoy flying squad things!

So maybe that is it.
So Hang do ya need a break? MAybe not from the game , but maybe from the way of flying. Maybe try some crazy things. Like a Hurricane low level ground attack. Or Mossies. Take JU88s on a low level sneak around to a enemy base way behind the lines. The FDB are a crazy lot and most of them are insane enough to do something that may seem stupid!
Well that my thoughts of it. For what it is worth!!
