"Reward:
Full Member: 2 stakes
Senior Member: 3 stakes
Hero Member: 6 stakes
Legendary Member: 6 stakes"

The gap between Sr Member and Hero Member  is too high and I will recommend that it should have been as follow;
Full Member: 2 Stakes
Senior Member: 4 Stakes
Hero Member: 6 Stakes
I ignore legendary member since none of them were privilege to make the list on the spreadsheet.
