Since Gree seems to be imposing things to try to get more money out of people, I wonder what a war without gold usage would look like. Gree would still give the option to buy gold but players refuse to buy it for the month. I think those ranked at the top may not be at the top, but most importantly, I think that would be the end of the game for everyone because Gree would end up needing to lay off a significant number of it's staff.
Interesting.
