I spent some time trying some things out in the arena yesterday. I discovered, if you wanted a one-on-one, all you had to do was fly to the fringe of the mob and sure enough, someone else would fly out to meet you. On occasion a couple of planes would come out. So if you want a one-on-one, you can have it, but you have to put a little effort into it.
I also tried flying right into the heart of it all. That was fun on a different level. Trying to avoid getting killed and then reversing to chase the horde was great fun too. On occasion I would pick up one plane that reversed. Most of the time they all just kept going towards the other mass.
I suck as a pilot, but I am having a blast.
If you do not like or care for the WW1 arenas, that is fine, the WW2 arenas are all still there for you. There is no point in being a detractor. Reminds me of the whiny brat at the ice cream truck. You know the one. The one bawling about how he hates chocolate while everyone else orders it, looking at him like he is an idiot because he does not have to order the chocolate.
