I agree FAF and its balance being run like a black box oligarchy is bad, but it is working for now and what you are proposing would be far worse than current system (all the gappers (90% of playerbase) voting to balance around gap on every change and even asking for new changes based only on gap)
last patch did some unneeded changes for no reason too in my opinion (nerf air crash damage from experimentals for example), the problem with current system is that changes seem to come from nothing, and to outsiders it looks like no one has any say whatsoever about any of the changes except for the few people who are already part of this secret society controlling the balance, we are just expected to accept anything that comes out of the black box without question
like will anything on the feedback thread or anywhere else (that wasn't said by a member of this secret society) ever have any effect on the balance changes at all or is the thread's and balance forums in general's existence just to give us that illusion and let us talk about the now-set-in-stone balance that we cannot do anything about, like it is some kind of natural phenomenon that can't be effected by the likes of us and we can only accept it, and in best case scenario possibly what we say may be heard by one of members of secret society so that they can consider it if they feel like it?
not that I know a better system to replace it with but this is what it looks like from outside
