I would like to see HTC take a second approach and create a "Career" mode completely separate from the MA when you are on the arena selection screen, right under where you choose what arena, have a button that says "Career" ......you pick a country....and a position...IE Fighter Pilot..... Bomber Pilot....from there you go into a bunker that has links to hanger and such as would be needed..from the Bunker you will have training AI missions and Missions that are obviously progressively harder and more rewarding......the better you do in the mission the better the score IE perk points.....
after the tutorial missions you get online AI missions that are filled with live players...if the player count does not reach maximum it rolls using AI.....
similar to the WOWP setup...except for wait time...make it very short....
at any point you can change which country, but you will be like a day one noob and have to fly ALL the training missions over and start from scratch.
Leave the MAs as they are the (perks earned doing the missions in Career mode will be usable in the MA's)....add this type of game play........Aces High would be perfect.
In my Opinion
