Damage dealt scoring is going to factor into H5?

Iv never really paid much attention to Mobas so could some please elaborate on this Damage Delt, and how this will Play out in Halo 5?

Will this be a Damage delt/damage taken ratio replacing K/D, or is this just rewarding those who get one shots Yoinked by team mates, awarding the supporting player with the kill?

I don’t remember anyone saying it was going to replace the KD. It’s just another stat to look at in post game.
