Good job, you evolved and refined it nicely.
You are subtly trying to limit the effectiveness of GVs on the over all combat initiatives it looks like. Is it that good of an idea to try and "force" players into planes and GVers out of the way with our current low numbers and anger about the current things done to the GV game? If you liked GVs it would be obvious by having more two way spawns inside of each country for GV initiatives to follow air initiatives and to mount assaults. As they are, resupply against attackers, and easy to isolate if captured. Like your HQ and strat exposure, it may well get you called names on 200, but, you are exposing them for strat runners and missions. Bet you made sure driving to them will take grim determination.
Nice touch creating GV combat islands and a TT for them to GV away at and not greifing airfields. Interesting how your vbase bridging spawns between countries 1 and 2 "dead end" at ports. No ongoing GV or air initiative inland from there keeping GV's from being rear area nuisances. The real bridging is between airfields picketed by task groups and the ring around the base of the caldera. You didn't run the ends to ports on the north bridging spawn paths like in the south. You don't like GV's sneaking bases out from behind you anymore than I do by how you arranges your spawns.
Those task group ponds should be fun to watch over an evening to how things develop.
By no means will this be dull. Hitech does like having a few airfields with no spawns he told me.
