Crucible Ranking system?

[Frietbal]

I notice my teammates and opponents get worse and worse in 6v6 control. Is a ranking system implemented here?

Also is combat efficiency the same as K/D? It feels I die a lot more than my combat eff would say.

Combat efficiency is based off kills, deaths, and assists.
If you want to see Kill/Death ratio you have to look at 3rd party applications. Ranking system is also based off 3rd party ranking system.

They have changed the crucible matchmaking system several times, but if I remember correctly, then generally speaking once people are matched together they are assigned to teams to try to balance a hidden MMR all players have. Trials and I think the Survival playlist (the Glory one) have more to their matchmaking, taking into account your trials win record and glory rank respectively.

Combat efficiency is KDA, not just KD, which would be why it is higher than you think it should be.

Well I suddenly saw "prefers to match players of similar skill" in the description. So that would explain it. Thanks for explaining combat efficiency. I also noticed a small sort of achievement sound when I get credit for a kill such as an opponent standing in a vortex grenade out of view or so, which explains some of the kills I didnt notice before.
