As a former chess piece loyalist, I must say that when I first came to the game, I was by default put on bish. By the time I actually found out you can switch sides, I had established bonds with certain players that have really helped me out. It was great working with these guys all towards the same goal of winning the map. I had no reason to switch sides at that point.
As time went on, real life situations reared their ugly head, I found myself logging on less and less. During that time, I came to the realization that what was worked on really hard the night before was just either regained by the other guys or thwarted by a map reset. Fact is no matter what the map situation was, I always had one to play on.
In FSO, WW1 arena, TA or DA. Map resets dint happen. They are still populated for the reason to learn and shoot down red guys. Most guys that are bish in the MAs wont turn a chance to play in FSO just because they are usually bish and now the event calls for them to be knight. So why should it matter in the MAs?
People that daunt the cape and tights for their country need to come to reality that not everyone that logs in to the game cares what the war is doing or what the map situation is. Yes you still have tools that do switch or have shades to find hidden CVs or missions or pad scores but I can honestly say that 99.999999% of those guys that are known to switch are just doing it to shoot down bad guys and nothing else.
You adopt a country here and establish bonds with certain players...more power to ya. Although considered blasphemy to some, squad tours are a great method to find out that the red guy you hated for such a long time is really a nice guy and alot of fun to fly with. Its also healthy for a squad recruiting, being that you are having a greater chance flying with guys you probably wouldn't get a chance to fly with just sticking to 1 out of 3 countries. Also keep in mind that those guys that switch to your side are there to help you out. Not being able to switch sides is just totally a very very bad idea.
