We understand the map approval system has its drawbacks, so we have created a forum section for requesting approvals, edits, and removal of inappropriate/outdated/low quality approved maps. We are allowing players to request that their own or other's maps be approved, which allows them to be used in Ranked and Approved gameplay in multiplayer. (Naturally this means only multiplayer maps can be approved)
When a request is made to edit, approve, or remove a map, anyone can comment feedback on the request, giving their own insights and either fighting or helping the case at hand. Feedback may also come from staff members or game development, who while gets the final say in whether a map is approved or not, value community input.
