If I had to choose between server where the rates are 10000x and server, where subclasses are stucked - i choose 10000x rate server. Why? Because a lot if things that makes game unbalanced.
If you want to keep your server alive, in first month i suggest you to make only C,B,A,S grade thing donatable.. then when you'll get more players on the server, you can add enchanted weapons donatable..
PS.
Find good GMs, that now how to do ther job. Cause on Dragon Network server they aint good in what they do..
