First, I would advise 4 lives per hour.
Now Eskimo's objections:
The veteran players will prosper, the newbies will be out of luck: Unless the newbies fly with established squadrons or players (as they always should). Emphasize in the MOTD that this it is important in this setup to fly as part of a mission, with wingmen. It is up to us veteran players to get the newbies organized.
Balance will be an issue: Balance is almost always an issue, and it should be. I know that I am in a minority here, but I accept the fact that MOST historical situations were unbalanced and that it is equally interesting to fly for the outnumbered as for the outnumberers (for different reasons, obviously).
Slower planes for the underdogs, and all that: That is only an issue if everyone flies to furball. I think Sabre's idea of keeping a weeklong score (or turning on logging in primetime) will take care of this nicely. It will mean that people will actually want to fly realistic mission profiles in order to help their side win the week. If the side with the numbers and the faster planes wants to accomplish anything significant, they will have to commit somewhere at some time. If the underdogs fly smart, husband their resources, and hit at the right time, they can inflict some severe casualties on the uberdogs. The key here is (for both sides) to fly with a strategic goal in mind.
Base defence will be impossible: And about bloody time, too! Pick a setup in which there is no such thing as "base defence". Sabre mentions BoB and that would be perfect. The score at the end of the week would be straight Tonnage on Target - LW losses. The higher the score, the bigger the LW victory. Just like the old SPI (TSR) BoB game (board).
I think this absolutely MUST be tried. Get people to fly with a strategic purpose. Notice that when lives are limited, AND there is a clear goal for each side, sacrifice becomes meaningful. Risk becomes real, as always happens when there are stakes to be had. That creates tension, which for many (most?) of us = a great time.
Now this kind of setup would require a bit more investment than usual on the part of both the CT team and the major CT squads. Lets agree to turn on the logging for Sunday, Tuesday and Wednesday prime time. Lets plan missions, lets try to get things done and win the game!
I am very excited at the prospect of a BoB setup which does not degenerate into a Dover Calais furball. This might just be it. I am also looking forward to a setup in which a flight leader decides to abort a mission because of unexpectedly strong oppostion. I have never seen that outside of S3.
But Sabre!! Be sure to give bombing the lion's share of scoring. No bombing, no score.
I'm sure I'll think of more to say later:D
