KDR is not really relevant to balance. There are two goals in a match.

Goal 1 is to win.

Goal 2 is to make isk.

Most matches come down to MCC, rather than clones. In such cases KDR is pretty irrelevant. Kills and warpoints are much more accurate indicators of someone's value in the battle. Though there is no perfect measure for contribution to Goal 1. KDR isn't often one though.

Goal 2 is defined by isk loss vs isk gain. Obviously if your gear costs more, you should die less. Otherwise how does it help you with goal 2?

Risk vs reward means that if your reward is the same (reward being isk, not K/D), your risk should be the same. So you should on average lose the same amount of isk per match. If you gear costs 5 times more you should die 5 times less.

Where will the 3.000.000 SP that I have saved?
Any advice?

I don't understand that you make This hotfix whereas the prority problem is the lag and the low framerate.

You Can create ail the hotfix that you want, It is very difficult to find fun in This game actually.
