don't really see an issue. You still have to defend the base anyway. It's not like once you take a base no one is allowed to attack it or something. What's the difference if he attacks it or someone else? Also, it's not like anyone has to guess where a weak point might be in the line. All you have to do is look at the map and look at the roster. 1 person isn't going to take a base, heck at times I'm amazed that 20 people struggle. though to be fair, there are different motivations when alot of people are flying directly over the field. I guess it's going to boil down to how serious you want to take the game. Not even going into possible coincidences, in that maybe finding friends/squadies flying for other country, or just boredom. I just can't seem to find a big deal about it. I would also like to add, there is absolutely nothing wrong with changing countries to fight the horde steam rolling bases.
