Any thinking person who has been in this game for even a short time, has to question why spend that kind of time and effort on maps, planes, and all that code for 10+/- guys. That arena gets used less than the Green (which I happen to enjoy). It just seems that if you we're going to spend that time and effort, why not on something people will use?
The WWI arena is not just for WWI air combat. It's also being used to test out new things, such as the new damage model, which will find their way into the WWII arenas. So, it's not a waste of time and effort for "10+/- guys".
