Sorta on the fence concerning inflight radar. Kinda hokey, but it DOES make the game more "productive", since we don't have to waste a lot of time chasing friendly dots. Also, it does give buffs a very valuable strat target. I'd like to see tower-only radar, with inflight sector counters, and have the sector counters survive HQ destruction.
SuperAck definitely needs work, but it DOES prevent SuperVultchFest, and gives buffs a reason to live. For now, soften up the ack a bit, and add multiple spawn points to make vultching more difficult.
Keep the three countries. I've played AW, WB, and WB HA. For my money, three works better than two or four. When it get to be 2v1, defect to one of the 2, and start a new front between them. You only have to wait an hour to come home.
