A lot of people would like to play more if they could find and get into fights quickly. The WWI arena and the DA are great for this if there's people in there but I suspect WWI's not used as much as it could be because people want their scores to count, they want to earn perks, they want to fly their favorite ride, etc., etc., etc.
I propose HT get rid of the current EW and MW arenas and set up EW, MW and LW fight club arenas set up just like the WWI arena; three airfields (one for each country), nothing destructible and killer ack. No radar to go down or be taken out.
Allow scores to count, perks to be earned and spent and carried into the MA. Leave GV's in these arenas with spawns to the center of the arena and a "safe" ring whereby if you exit the combat zone and the safe ring you land your kills. Let attack planes carry ord specifically for anti GV work and to allow for use of flaks. No bombers outside of light, single engine types.
They can't be used any less than the current EW and MW and would be easy to implement. Seems like it would at least be worth a try and maybe could be used as a free to play option by further restricting the plane set for the free players.
