If your favorite server was removed then it was because it was losing players and eventually going to end up completely empty. Unless you can prove that the map is gaining in popularity on other servers, it will not be coming back. Valve servers do not count. On January 23rd 2014, Valve defaulted quickplay to official servers which killed off all but the most popular maps. Before this, we used to have every type of rotation server and for less mainstream maps such as gravelpit and barnblitz. It is up to you to keep your favorite server filled. We have done everything humanly possible to make sure that our servers are the best and that's why we have way more players than everyone else. If you can't do that, then you should complain to Valve to stop quickplay from defaulting to official servers. Even if we had unlimited money, what's the point in keeping a server that no one wants to seed? Why can't we just keep the server up until it is completely dead? Because everyone would have removed it from their favorites and it will become 100x harder to replace it with something else.
