My turn, IMHO, I don't really like the perk scheme. I understand why it is necessary but I would much prefer to see an RPS. HOWEVER, I do respect the point made by J_A_B and certainly wouldn't want to see players leave the game because they couldn't fly the ride they enjoy. SO, here's another suggestion that may solve a few other problems. We've all read the threads about how over crowded the maps are and the amount of lag that is introduced when many hundreds of players log into the MA. So why not have multiple MAs running revolving plane sets but ALWAYS at different points in the war. MA #1 might be running early war while MA #2 is running middle war, while MA #3 is running late war. Each MA progresses through the entire plane set but at different times. If there aren't enough pilots to justify 3 MAs cut it back to 2. That way, you would always be able to find your favorite ride, lag and over-crowding would be limited AND every now and then you could log into an arena and fly against a 100 other ME-262s which will never happen under the current perk system. Remember the day Me-262s were perk free, everyone was flying them and most folks were enjoying it.
I know this would get blown out of the water when the BIG maps arrive because there you will need the large numbers but until then, this could solve a few problems and continue to make game play fun for all.
