Personally I found GV spawns to the old strat factories to be annoying... You would spend a good while in a slow bomber getting ther to blast the crud out of it and by the time you got back to base a few guys in M3's would have the strat right back up. I'm not saying this still can't happen with goons but I find less people are willing to fly them as they are to run a quick M3.
Not saying though that this wouldn't make for an exelent tank town item as long as it had nothing to do with the strat.
would be fun hunting through this city.
