OK, until recently I worked weekends, that is why the BoB scenario was out.
The reasons I don't sign up for them are, I'll admit, a mixture of my uninformed guesses as to how they go as well as imbalanced or unenforced rules.
For example, from what I little I read of the BoB scenario, I gather the Bf110C-4s made mince meat of the Spitfires and Hurricanes. There are a few reasons I think this would be the case, most of them beyond the reach of the people running the scenario. However one of the reasons I understand is that the Bf110s were flying in a totally nonhistorical fashion, e.g. providing very high top cover for the bombers.
The other thing I understand, and this may simply have been Allied whining, is that the RAF was hampered by a radar system that was far, far inferior to what the British really had in WWII and thus were usually having to attack the bombers, let alone the fighters, from an altitude disadvantage.
How do the events run? What I have imagined right now is sitting around waiting for an hour or so, then uping in a structured environment and trying to accomplish the mission with very little enemy contact. If you get shot down that is that for the frame. Essentially hours spent for very little doing.
That is what I imagine it would be. Please correct my misconceptions as taking an A6M2 up against P-40Es and F4F-4s doesn't sound very fun considering how over tough those fighters are modeled and how weak the A6M2 is.
