I believe the /kit starter we should get atleast 3 diamonds because for new players they would have a better start on the server so they will enjoy it more and tell there friends to come and play. I know its not a lot but it would help =)
It seems like a good idea since donors get kit diamond and iron.If you want i could report it to a staff member ASAP i dont think one will reply in a while.
If you would get diamonds in /kit starter then it would be easy to get rich on Factions and then many more would quit
