First of all, it isn't true to what mysterious lie they have beheld us when they said you can up stats with donations.
Next, a db room would not work because if it spawns MvPs then it would cause a shift in economy.
Finally, donations aren't exactly that out balanced. They give an edge but nothing more. It just depends on how you use your character, if you think negatively about yourself all the time. How do you expect to defeat a donator?
Good luck and best wishes.
