Problem is people either want high rate or medium rate servers, so the community is always between the 2, add in most of the fly by night server just out looking to make quick cash and mir 3 is in a bad situation.
If your looking for a server that's updated a lot then try Samurai, been up for about a month now and live for the last 2-3 weeks. Its medium rate, not too slow, not too fast, a lot of updates done daily. Only thing lacking is the user count at the moment but hopefully it will pick up soon once people realise the server is here to stay as long as people want to play it.
