The real issue for me is: The devs make content aimed for "One Public only".

ARR aim only for casuals and low man groups. 90% the content is for 4 man.

We need Content for Small FC, Medium FC and Big FC.

Ask for a massive amounts of dungeons is unrealistic because Create a Full Dungeon can take 30 Days of work. But make "One Boss battle can take 1 or 2 weeks with a competent group work".

We are talking about the Mastodon "Square enix" a company with enough Money for pay for Quality. This is not Sega or another Poor Company. Square enix have enough resources for make this posible.

Each 5 Weeks (A group of Work of 10 people will be Needed for this).

One 8 Man Boss Battle. Rewards. ILV 80 and Tomes
One 16 Man Boss Battle. Rewards. ILV 85 and Tomes
One 24 Man Boss Battle. Rewards. ILV 90 and Tomes.

Each 3 Months. (Another Group of Work of 16 people will be needed for this)

One Full Dungeon For 8 Man. Rewards. Ilv 85 and Tomes
One Full Dungeon for 16 man. Rewards. Ilv 90 and tomes
One Full Dungeon for 24 man. Rewards. ilv 95 and tomes

Each Month. (Another Group of work of 8 people will be needed for this)

One Boss FATE Fight. This Fight will have a minimum duration of 35 mins with over 300 players. This Fight will Auto Start two times per day. 8 Pm Est Na and 8 pm JP Time. The boss will depop after 120 mins. Rewards ILV 75 - 86. Housing items, Minions, Vanity Slots, Aesthtetician Items, Mountures, Gil 50 - 75k per win.

We can Access Via Party Finder / Duty Finder to this content

The reward System wil be Individual, so we can avoid the treasure pool dramas.

If a person is removed from the group, that player CANT rejoin this group.

All this Content Share Cooldown with Levequests and have 24 hour individual cooldown after of receive the reward.

Doing this. Finally the people will start Run Raids with their FC buddies. You make content for all publics, casuals, Average players and Hardcore. You Flood your Game with Content, you keep reasonable lockouts for the hardcores dont let behind the rest the public very fast.
