To ensure players in all regions are able to have a healthy matchmaking experience, with quick matchmaking times wherever possible, map selection options for each region do vary. Wherever possible, we want players to have the choice of selecting which map they want to play, but our priority is ensuring healthy matchmaking times.
AS, SEA, KR/JP, EU, RU: Full map selection or Quick Join (1 of 5 random maps).
SA, OC, NA: Full random. Sometimes Featured Map is enabled in these regions only for a short period of time, especially when one of the maps get remastered.
