I'd like to add a comment to those that may or may not share my opinion on the matter.
This thread is about gameplay balance in the FSOs, vs lacking planesets, and finding something that "works" between the two extremes.
My comment above is 100% directly related to this topic, as I feel the FSOs setups are lopsided, uncivilized gang bangs most of the time. This is the gameplay part of the issue. I don't think there is much anymore.
There was a time when spit5s ran across 190A5s, had a fight, and parted company. Now the 190s break off, chase the spits outside icon range for 50 mi and vulch them as they try to land. Quite a bit of difference, as far as gameplay balance is concerned.
To point this topic back to the "answer" to this problem, I don't know if any amount of rules ro changes can revert this behavior. You can't create a rule if you can't enforce it, and most rule suggestions just can't be enforced. It's simply the result of too many MA dweebs influencing the FSO over the years. The attitudes have totally about-faced and the end result is it's no longer fun on Friday nights for me.
I have suggested a couple of ideas before, on similar topics, but they wouldn't work (rotating squads in and out to reduce the player count, or removing all bomber formations and putting a single pilot in a single plane, adjusting side counts so ratios are the same) but the end result is that no idea that has been suggested will change anything so far.
If my previous post sounds bleak, it is merely reflecting my hope for a better FSO at the moment.
