Is there currently any way of cutting down the pilot transfer/replacement rate? It would be really cool if loosing squad mates actually caused an attrition effect and it took time for new pilots to transfer in, rather than getting instant replacements and always being at max strength.
It would be pretty challenging and really would not produce anything noticeable. Whether you had twelve, ten, or eight pilots available you would still staff your flight of four. It would not really produce any noticeable impact n your campaign unless your squadron was completely slaughtered in a short period of time.
What PWCG already does is replace your lost experienced pilots with inexperienced ones. You had a pilot that was a veteran, or at least normal. It took several missions for him to rack up some time in the air and victories. He is finally at a skill level where he can contribute and then you do something stupid and get him killed. Now he is replaced by a novice. That replacement system makes it very much worth your while to care for your AI pilots.
