The matchmaker team will be trialing a slightly altered approach to selecting maps for the 1v1 ladder map pool starting in September. The pool will be focused on high quality competitive maps and eliminating the more extreme ends of the previous map pools, such as very small or large maps and extremely high reclaim maps.
We hope that the approach results in more consistent game lengths, maps that allow diverse strategies and an overall more consistent ladder experience. This approach should also make it easier for newcomers and returning players to learn the maps and jump in.
As an exception, we will maintain the inclusion of the smaller maps for the lower rating brackets, as feel that they offer a great gateway for newer players. We'll be monitoring the effect of the experimental approach in the coming months and make adjustments if needed. Furthermore, we would appreciate any feedback and encourage you to post it in this thread.
