Simple.

What Hunts should have been from the begining and anyone who played FFXII was expecting. Hunts should be party content, forced spawns individual to each player.
Easy and simple.


B Rank: 1-4 man, 5 per day. (15 diferent marks per day, 5 per each board)
A Rank: 4-8 man, 1 per day. (3 diferent marks per day, 1 per each board)
S Rank: 8 man, 1 per week. (3 diferent marks per week, 1 per each board)

Players in the party will all get the reward, just as GC delivery and supply missions, marks for everyone in the server will be the same, just the area of spawn for them will be diferent, having a big array of diferent marks will help maps to not get full of people looking for the same mark.

Even when is a party triggered spawn, anyone in the area can help, but the reward for those people will not be the full reward of course.

The rewards should stay but the prices of raid items (oils and sands) should increase.

Think about them as harder leve allowances for parties in which any player can participate even if outside your party.
