Every FPS share the same basic concept, shoot to the enemy and kill him, so kills and deaths are occurring very often.

Generally in every FPS kills and deaths count only towards to your stats and have no impact on the way you play the game, but DUST is different, you have to pay for your assets (and i like this concept), but ISK payouts are not balanced to your effort.

Let me explain better with some examples:
My STD fits cost average is: 20k isk
My ADV fits cost average is: 60k isk
My PRO fits cost average is: 190k isk

My payout average is; 210k isk

This mean that i can die:
10 times in STD or
3 times in ADV + 1 STD or
1 time in PRO + 1STD.

In a game where deaths are frequent like a FPS you should be able to die with your best asset at least 2 times and still make profit.
I have had only a biref experience with EVE online, but i don't think that death occurrs as much as in DUST.

Let's assume a player with a 1.0 kd/r, he should be able to use 1 PRO, 3 ADV, 10 STD and gain some isk (not a lot but a decent amount), 16 kills and 16 deaths.

How?
I think there should be some kind of isk multipliers at the end of the match based on your WP score.
Each multiplier should be at 500 WP
Something like (random numbers):
500wp x 1.1
1000wp x 1.2
1500wp x 1.3
2000wp x 1.4
2500wp x 1.5
and so on till a cap of 2.
WInning team gain a +0.1 on all multipliers, losing team -0.1 on all multipliers.

In this way the game will pay your efforts and you will gain something more if you give something more.

It's not my problem, i have enough isk to run proto if i want, it's a general problem, probably you don't care, but if you place 1st in match there are 15 other players under you that gain less isk than you and other 16 on the other column that gain less isk than you, try to open your eyes and look the other results and not only yours, it would be too easy to judge only with your point of view.
