Despite its tendency to randomly restart (which I assume is why it was removed), Goldrush was one of the most popular maps on the rotation and people have constantly been asking why it isn't in the rotation anymore. It was a server-filler, and I know of at least one person who stopped playing on the server completely after Goldrush was removed. I've also noticed many people on the server complaining of a lack of map variety. I think adding it back to the rotation would be a net gain for Skial.
