As far as I can tell, no. Your MMR increases, but it doesn't appear to ever decrease. So once you break into the top bracket, you're stuck there.

Well i had the exact problem with my magden. Always duo or solo and high mmr.
I did reroll him to a healer, the thing about healers is, that you can pump out 3 mio healing carry your team and still only get 1300 points in DM. So after like 2 months of regularly healing my MMR went down so much i was placed in cp200 -500 newbie BGs.

So yes MMR declines but you have to hit lowest score in the game over and over again.

been using the random battleground daily to level a group of characters...they're all still below level 50...

once I reach level 50 - will my mmr re-set for the level 50 and above battlegrounds?

I do think it can go down

Top bracket sounds like its something hard to achieve when in reality you get thrown in there after 10 games.

It doesn't go down but you will eventually see different players because theirs will go up.

This is hilarious to read. You got one person, eye witness experience with their own character that describes what they did to make it go down and that it Does go down.

And then After that, lots of posts -'It can't go down', 'It never goes down', 'it can only go up, never down'

I needed a good laugh

Where is this eye witness experience? Quote what you are talking about.

If you are referring to the player saying they re-rolled their character into a healer and then started getting a low score, this is not evidence.

I did the exact same thing last year and I did not get those results (damage NB turned into a healer).

This is one person's experience versus one person's experience. I would need something more to convince me it goes down.

So it is not hard evidence but I'm gladdened by your response as you have given me a good laugh as well. We all need some humor in our lives.

I’m not sure how it works behind the scenes, but even if it cannot actually go down, everyone else’s is also going up, so in that sense yours can go down relative to other players. What I mean is, other players who are less skilled are joining your mmr bracket every day, and (unless you’re at the peak) many others are also leaving your bracket to go to a higher one.
