My idea, since RoS expressed concern about the most active people being likely to win, is to break it into brackets. So, level 0s are competeting against 0s, 1s against 1s, 2s against 2s and so forth. That doesn't mean taking someone down from another level doesn't count. To the contrary, they either count for more or less. Each bracket will produce a winner, so there's the possibility of a prize for each level. Right now, I'm thinking energon prizes, heavily weighted to the lower ends of the bracket, because the higher you go, the less likely you are to need the energon. That gives us 6 bracket winners. Over all hunt winner will be by highest score. I think the most effective scoring system is the old "lower level kills are worth less than your level kills are worth less than higher level kills." Typically, it's a 1-2-3 scoring system, but a 1-3-5 might be a little more fair, as some of us are still going to kill a crap load of lower level guys. Especially RoS and N_V. The person with the most points wins.
So, if a 2 takes down a 3, they get 5 points. If a 5 takes down a 4, they get 1 point, and if a 3 takes down a 3, they get 3 points. 5's obviously can't get the higher level points, but they can offset that by simply killing more, any 0s can't score below 3, but they offset that by being really easy kills.
And with the brackets, even if the usual suspects wins overall, a lower level player gets bragging rights for being the best at their level.

Thanks to Chaoslock for pointing out my error.
