Currently the perk system rewards those who kill other players, destroy objects, resupply objects, and capture fields. Only one of the four rewards has anything to do with furballing, so the current system primarily promotes toolshedding, not furballing. The system also has greater rewards for those who fly for the side with fewer numbers, while lessening the rewards of those on the side with greater numbers. So, the system also rewards the underdog, and promotes a more balanced dispersion of players, at least among the players for whom perks are a motivating factor. This is, in all honesty, probably not the majority, as many players have accumulated hundreds, thousands, or even tens of thousands of perks. But, regardless, the rewards are increased uniformly, whether the underdog is resupplying, blowing stuff up, taking fields, or killing players. Again, 75% of the rewards go to those who are not engaging other players. No bias toward furballing.
What you describe, Traveler, is just a way to ensure that the side with a numerical advantage, maintains that advantage, and attempts to penalize those who either don't fly for the side with numbers.
As an example, let us say that those of us posting against your idea are flying for country X, which has half the players of Y, and Z. In defending against your horde country (the one which will win the war- doesn't matter which one), we kill 2 of you for every one of our deaths. Every one of us captures a field, resupplies a field, and destroy 10 objects each in the course of each capture. Your team, due to the odds, can only manage a single kill every second sortie, and only half of you are able to get captures, resupply a field, and destroy only 5 objects during each capture. Despite the fact that we accomplish more per player, and do so against worse odds, we would receive nothing, while your country, which won only by overwhelming numbers, even though they accomplished less per player, in a situation that favors your countries, would be handsomely rewarded. What that would lead to, is more players changing to the country with the most numbers, creating a more difficult situation for us, and an easier win for you. That would, obviously, perpetuate itself, to the point that the game was not enjoyable to play, either by being without any challenge whatsoever, and slight rewards (due to the perk modifier, and the fact that your numbers mean fewer targets and opportunities for every single one of your teammates) for the "winnars", and by being an insurmountable challenge to the players on the lesser numbered countries.
In short, it's an ill-conceived, pointless, worthless, concept, lacking any traits which might promote anything other than severe imbalances in numbers, and terrible gameplay.
Sincerely,
