I know the perk system is already in place to increase variety by positive incentive, but I had a thought on how it might be bolstered and perhaps even added scoring into it all without penalizing those who don't want to participate. The seed of the idea came from World of Warcraft actually, a game I also play. In that game, a fantasy MMO, there is a quest that is available each day to go and complete one of the dungeons on hard mode. For doing so you get a little bit of a bonus, but nothing forces players to do it.
What I thought might work in AH would be to have, each day, a fighter, bomber and vehicle randomly selected by the server that would award double or triple the perk points and score, whatever is determined to be balanced, for kills and structures destroyed while using it. The units would only come from the ENY 15 or 20 and higher units so as to avoid having a "P-51D day" or "Spitfire Mk XVI day" when we hardly need to increase the numbers of those in the MA. There would be no negative to ignoring it and flying whatever you liked, but for those looking for a way to boost their perk points or score it might be that needed push to get more P-40Es and Ki-61s and so on in the AH skies.
Thoughts?
It also strikes me that there is a potential, negative, reciprocal of this. Instead of "Fighter of the Day", "Bomber of the Day" and "Vehicle of the Day", replace it with "Target of the Day" and randomly select a unit with an ENY of less than 15 for which killing it rewards extra perk points and score. I don't like this one as much as it turns some players into the hunted just for their preference in gameplay.
EDIT: Fixed typo.
