Ubisoft has announced that some map rotation changes are on the way for Siege in both the ranked and casual playlists. The ranked playlist will consist of the same 9 maps that are used in the Pro League. Meanwhile the Casual playlist will consist of 15 maps with some maps leaving the rotation entirely.

Some fans seem to be upset by this news but we also understand the developer’s point of view as they continue to try and polish and refine Siege over time. We’ll see how fans react once the playlists are live.
