I saw some great suggestions a while back that could make old S ranks more fun overall:

1. Sync them all to 70, sort of like reverse FATES. This would ensure multiple people can participate like with SB S ranks or Ixion.

2. More transparent spawn windows. Right now the most efficient way to track S ranks is with third party tools. When nefarious players mess with those timers (as they have been doing) then other hunters have no idea when the spawn windows are open or when to attempt S rank hunting. Integrating spawn timers into each zone's hunt NPCs, even if it's just a simple "XXX S rank is far away..." or "XXX S rank is nearby!" alert for when the window is up, would really help so hunters don't have to rely so much on third party timers that can be tampered.

Hunts, when done properly, are a great community activity. They're also basically the only reason to leave town anymore. I really hope there are some improvements to hunts so everyone can benefit from them.
