Are you sure? this isnt a regular rift we're talking about, these are GR's that are available for leaderboard ranking. If this were the case, people would do 4 man groups on a high GR, and leave at the very last moment and kill the GR with 1 or 2 people and get a very high leaderboard ranking on those boards.
I agree. When you complete a GR the reward screen shows everyone that WAS in the rift, regardless of who was in the rift at completion. The monsters don't seem to get easier when a person leaves. I hoping the community could shed some light on it.
So, do GR's scale back when a player leaves your game or is that GR going to stayed scaled 2,3, or 4 man when the GR was activated?
