make all the donor scrolls untradeable,
Give more perks for donators, and maybe drop rate potential depending what rank you are.
this way people wont donate and go to duel arena to just lose their bank and quit.
and the eco's would have a hard time to collect and hoard the donor scrolls which they control the market with. Just a tought, peace!
dont have any items in store thats tradeable for donators, only perks.
