Q: How are you changing the MMR […]?

Q: [Will Battlegrounds get] ladder resets?
A: Not planning on ladder resets
Q: doesn’t [the MMR change] means that the “max” MMR will also be raised by a lot? that is, people reaching 12k and stuff?
A: I assume people like tides will keep climbing yes, some people are not gaining points, they still won’t gain if they are at the correct mmr
