Ubisoft have made a couple of server updates to the online ranked matches of Rainbow Six: Siege that is supposed to improve the quality of the experience. The problem was that lower ranked players often got to meet really high level ones, but by changing some parametres, they expect an increase in matchmaking queue times, but this will improve the balance and quality of matchmaking.
The PS4 and Xbox One versions were updated a few hours ago, and now the PC version has been adjusted as well. Have you noticed any differences and have you encountered problems with the balance of matchmaking in Rainbow Six: Siege previously?
