Well I realy think a lot more players would come.. and when the popularity raises.. you can always raise the prize a bit again but for now Graal has such less players than before... it should get more populair realy! That would also motivate Classic servers more to improve and stay up-to-date..
Also it would be very sexy if they'd pay Classic Managers
The motivation of getting something for what they due will encourage competition between servers.. Managers could decide to pay their staffs maybe.. Thus it'll higher the quality of the servers, and in turn, higher the population of the servers! Therefore, it would higher the revenue of the server... Or... The revenue of Graal

Perhaps, even, GO should pay the servers proportional to their average daily playercount
