Leaderboard will change constantly

Even after the MMRs “settle”, you still have to play with whoever is queued up at the moment and time of day when you are. And you can still get teams like the following hypothetical match, where a top player has an MMR near 2000:

Team 1
MMR 1,800 *
MMR 400
MMR 190
MMR 185
MMR 150

AVG MMR = 545 (expected to win)
=========

Team 2
MMR 750
MMR 700
MMR 700
MMR 320
MMR 205

AVG MMR 535

The 1800 MMR play will probably lose, and will have his MMR lowered some, as I understand it.

So I am guessing that the leaerboard will be constantly changing week to week…UNLIKE how it has been.

No, the latest matchmaking changes will not produce matches like this.

The leaderboard will continue to fluctuate until each player’s deviation narrows.
