I just prefer a large open world environment. Probably does not make sense to anyone but me. The numbers seem to be about the same as they were in 14-15 when I played and large maps worked just fine. My all time favorite map was Fester, followed by Ozkansas. I always hated when the small maps cycled (with the exception of Crater) and would even switch sides to help whoever was winning win faster.
I liked festers map as well, however, it wasn't even remade for AH3.
The problem with large maps is that late at night, with less than 30 people logged in, and less than 10 in the air, the map allows for such spread out action that it appears that there is very little action. I see this happening on bowl MA all of the time. If you are new to the game looking for some action, you will look at these maps late at night and see pretty much no action on the map. It makes it pointless to roll. If you do roll, you might fight one guy every 30 minutes or float thru the sky never finding anyone to fight. Smaller maps make it much easier to consolidate action and make bigger fights with less people. Also, large maps take much longer to win, and can stay up for 4-5 days. This makes it very boring for people who join the game every day playing the same map for a while. At least it does for me.
Just my opinion.
