The old GP system won't work since many high GP players are playing less and less now. If you keep losing you will go into a lower tier and then you should be able to win and climb back up.
I'm kicking 12 mil GP players out of my guild for not logging in each day. I always have to keep spot 50 open so new players keep going and I can kick the inactive ones out. This game 9 years old, it won't last but a few more years (the grind will get worse the older the game gets as more gear is added). When admin/developers stop paying attention its game ,it's because the game isn't making the money it used to. They will focus more on other projects that are making more money as time goes by.
