Weekend Classic Matchmaking

I’ve seen it answered both ways, looking for clarification….

I know that the reward tier will be based on your highest rating of the ranked season. So if you hit 800 you will be locked into Gold II unless you get to something higher. No matter if you drop to something lower.

For matchmaking however, will you be facing people at your current rating, or at the tier you were locked in at?

I’ve seen some people say they are tanking so they will play people below their true rating…. And I’ve seen some people say you are going to be placed in a pool of 100 players consistent with the reward tier you are in. No matter if you tank to the 400s before the program starts. Which is it?
