Ok then break it down by MA experience.
1. - Enemy GV gets into the town before anyone spawns from the town hanger.
-How is the hanger protected from that lone GV heading to either shoot down the hanger or camp it making the defenders sitting ducks? How is this fair to anyone?
2. - Friendly GV or GVs gets out of the hanger and mounts the ring hills with a long range sniper shoot to the spawn.
-How is this fair to the spawn GVers who are now sitting ducks?
3. - Town center is 2.5 miles from the airfield GV hanger. The GV spawn is 2.5 miles from the town center.
-When you build a terrain, there is a tool that lets you setup circles with a radius from .1-100 miles. Terrain builders "usually" make the town defenders drive generally the same distance as the town attackers. Is that an unfair race?
When you think about building a terrain, a mistake that muddies how you setup things like this is you will unconsciously think from the perspective of only your country and how to defend it. Not, how is the a fair setup for the defender and attacker. Both are paying customers and your terrain is being used by your friends and potential enemies.
