That’s were efficiency based will play the roll. If a player stats drop significantly then it’ll register it as similar to AFK or Jumping off the map to gain reputation. It puts the player in a separate lobby with players that do the exact thing. If you raise your elo within that season, it places you in that elo rank for the remainder of the season. If it drops, it still puts you at that elo you were highest at but matches you with players who’s combat rating dropped. And to make sure players aren’t jumping off the map or afk, there will be a penalty for deaths not made by player actions. Staying afk without switching weapons and ads will penalize you into a lobby with similar players. I’m sure bungie can make this happen. Adding on: To gain reputation, you must have stayed in battle or in a combative position for at least 3 seconds and not from architecture or environmental issues. Otherwise, you’ll be placed on standing positions that gain no rewards based on performance. Not even glimmer drop. Not even exp. The only way to earn rewards would be to raise in elo, to win matches, or to increase efficiency rating. Rewards are not penalized if your teammates leave, however if you pair with the same teammates and they do it again, it can register as a penalty. Those teammates that left will also be placed in a separate lobby with similar players that have “connection issues” with similar elo, and combat rating.

People wouldn’t jump or afk to reduce there elo they’d likely sit back and just let the OPPs cap zone
