Currently we have no plans on opening a new server, no matter how many threads you make, simply because it takes a lot of time to start and manage a new server - time that we currently do not have.
You are saying that it is "impossible" to hunt on the map because of the number of players, but in reality it isn't. If you were to start exploring more hunting grounds instead of just expecting the popular ones to be empty, you would notice that there are a lot of areas that are left empty, while the more popular ones are crowded. If you stop being lazy, the player amount really is not a problem.
