in the way we are thinking, donators have no advantages in the gameplay, so stones can get to higher levels as quick as Donators can, now. (If I got your reply wrong, I apologize for that)Understand that donators having more available items to what the Stone members have is (to my knowledge) against the EULA. It wasn't taken away because the staff thought it would just be a good idea to remove the kits, it was taken away to abide by the EULA change. If I am wrong, please correct me.
