Just some suggestions:
1.what about adding some boss leader boards showing like the top (1-10) people for that certain boss e.g olm, vorkath, hydra and so on.
2. possibly buff the dr for different donor ranks aswell because found out only get 10% extra dr when crystal rank and that's 8k donor status imo think emerald+ deserver more dr than what they get, again just a suggestion highly expecting this one to get ignored but worth a try.
3. maybe add emerald zone and ruby zone aswell because there really isn't much difference between sapphire donor emerald donor and ruby donor apart from the weps and a little bit more, again just a suggestion.
