For me it's about engagements.
Fester's map is more engagements in far less time than BI or AKD and even the improved Trinity. YMMV.
The climbing/driving around on autopilot part holds no interest for me. Just a personal fault, I guess.
Bottom line is ALL the gameplay is still allowed on Fester's map. You can still do any/all the things you want/wish to do on it.
However, the other big maps, no matter how you slice it, offer less engagement opportunity due to distance between fields. This is even more of a problem if one wishes to fly the earlier/slower/shorter-ranged part of the plane set (a personal choice, of course).
So once again it comes down to that. Fester offers the same opportunities as the other big maps PLUS it is much more friendly to early/mid war type aircraft looking for engagements PLUS the shorter distances allow for more engagements for the engagment-centric (me

).
Seems to me that's good for all concerned. As opposed to BI, AKD and ITrin which are good for some but definitely not for others.
Dear Cod, please hurry HTC up with TOD. It's got to help one side or the other. I hope.
