No, I'm trying to improve the game, I'm not at all trying to force behavior that is unreasonable or unacceptable. I'm not trying to do anything contrary to the accepted standards or practices, because there IS no accepted standard or practices. And neither am I trying to force people to play the game 'my' way.
Theres a difference between giving people viable options in play style and 'forcing' them on people. Have you ever stopped to consider that the difficulty of finding a decent sized fight that isn't a horde could be called forcing a style of play on others? No, you didn't, that concept is far beyond your limited cognitive abilities.
Darbar is a longstanding game feature, that serves to inform players of the presence of groups of enemy and friendly aircraft, and their estimated strength. As far as I can remember, you've always been able to fly below darbar level.
Since we don't know the rationale behind the darbar (to prevent base sneaks, to encourage fighting, etc), we can't say if this suggestion is contrary to that accepted 'standard'.
However, if you insist that simple change is perversion (which you likely will), then there aren't words strong enough to describe what you're trying to do to the game. The home page even says "the best WWII and WWII combat experience". No where does it mention postwar 1946 arenas, or 'experimental aircraft that never saw combat in WWI or WWII'. Arguably, all your requests for Do 335's and other post war aircraft are perversions of the entire game, not one individual facet of it.
You are simply trying to portray my suggestion in a negative light for petty and selfish reasons of your own.
