I like varying things in AH, so I like the idea of FT. I'm not 100% for isolating it totally. A big island in the middle on one map suffices, has the same effect but more fields (to retake a field from once one is lost).
However what I don't like about this map is the fact that the fields start on a 45-degree hill at 4k (5k?). That's just dumb. As was mentioned the guys respawning have the advantage over everybody that just killed them. I'd rather the fields were dropped to a more respectable 1k to 2k (enough for a shallow dive but not so much that a plane with speed can't zoom up to ya).
Tank Town doesn't spawn you instantly behind the enemy GV, why should Fighter Town drop you higher and faster directly above the enemy? Seems to be bad form, if you ask me.
Make folks climb out and make folks able to glide back if they can. I once lost 3 parts and had 1 minute of gas left but was almost unable to land because I had to climb 5K up a hill to land. That's dumb planning.
P.S. Yep, I landed, barely.
