I was going to make the same point that London did- I go back and forth between caring about my points and not. When I am watching them closely, I tend to lose a LOT. when I dont care and just have fun, I gain significantly. For the last month I decided not to worry about my points and have gained over 3,000 since then. Now I am just amused that I actually passed 10,000, although I probably wont stay there-
One suggestion I have, is when players complain about how many points they are losing, just remind them that it's part of the game and that they WILL get them back eventually. You could also suggest that they turn off the gameme stats in game- I believe its !gameme_vanish 1 or something like that- that way, out of sight, out of mind
