Getting a free month/year for ANYTHING you do in AH will change AH from being a game into a strict competition. This competition will not improve gameplay, it will simply increase the desire to do anything possible (spawn camping, vulching, flying timid, and staying above 400ias) to improve one's score.
AH is like golf, any improvement should be based on the individual and not when compared to a score sheet that is so easily manipulated.
I left for a year when HTC started the cash award for the highest ranking player, the change in attitudes was significant.
Giving awards for Tournament of Champions? Why would you want that environment anymore competitive than it is now? As it is too many feelings have gotten hurt and a CM lost his position because of it. Heck, you guys have to film your sorties because no one trusts each other. I'm still hearing rumors about people using Teamspeak to give squads an edge because it won't show up on films.

Yes, adding money to the equation would surely make AH a much friendlier place
