The only problem with these is that Destiny's pvp caters to k/d already. In the crucible, kills gained more points than anything else could and it was confirmed that Control in pvp didn't even require taking a single control point to win. The game is so heavily lopsided that fundamental game changes would have to be made to complement your system. Not to mention that nothing can prevent you from having a low ratio, no matter the system, when half your party rage quits (and that happened far too often in the beta)... If bungie fixes the k/d favoritism in the pvp, I'm inclined to agree with your system. Also, it would be nice to see a damage dealt to damage taken ratio as well.

The fix you are refering to doesn't fix the fact that the entire control pvp mode is a glorified TDM that doesn't actually have an objective and almost completely depends on K/D to determine the winner. even with your system in place k/d will determine the score in Control ps: k/d and k/a/d is completely inaccurate to begin with. I have had multiple instances where I deal someone most of their health in damage and the duck around a corner or I die before being able to finish the job only for them to get killed before they can regenerate and I don't even get an assist for helping joe shmoe get a free kill. this means anything based on a kill ratio is ultimately flawed as well and the only true way to measure skill is a damage dealt / damage taken ratio and even then your score will fluctuate based on the number of rage quitters on your team. so unless you implement a heavy penalty for quitting a started match, the game scoring will always be inaccurate...
