I'll start this by simply explaining my reasons for both the 1.5 fuel burn and the re-arm rules.
1.5 Fuel Burn
This setup requires nothing more than a 100 mile combat radius, more or less, for all planes involved. I do realize that some of the Russian rides have short legs, but even they can be used effectively with this short distance. No, you cannot takeoff and leave the throttle firewalled the entire frame. That is by design. No, you cannot hang out indefinitely over the target. That is also by design.
Re-arm
Using only the designated fields for rearming reflects the logistical issues involved with rearming and refueling aircraft, plus the infrastructure necessary to support aircraft operations. These capabilities didn't exist right at the front lines. Airfields were certainly pushed as far forward as possible, but not so far forward as to make them vulnerable to enemy attack. Furthermore, the required infrastructure was not limitless, and consolidating services and resources at a select few bases rather than spreading them out all over created efficiencies that air commanders were quick to take advantage of. Last, like the fuel issue, it creates another complexity for the CIC to negotiate--another facet of the overall tactical problem.
Finally, these are simply two different tools I've used to create some immersion, a more realistic feel, and a more complex planning problem for the CICs. I've done this because I believe these characteristics add to the value of the event, for most of the FSO community. However, if the community wants a more vanilla event, then perhaps I'll get rid of them. We create these events for the playing pilot, not for our own egos.
The penalty for rearming at an inactive field is extreme. It is equal to 1 point per violation. As either side can achieve a maximum of 100 points per frame (115 with the landing bonus), each violation can reduce the number of points a side scores substantially. Typically with my scoring system, the sides average around 50-60 points per frame. It can, and has in the past, affected which side wins or loses the frame. If it was not so extreme, then a potential violation could be rationalized by players.
