This plan would make everyone happy with how they are planning how they are bringing out new raids and replacing dungeons with raids. This includes the players and the developers.


Redo some of the dungeons because there too copyed and pasted and keep those content the way they are. The area can also can be adjusted for the second raid area. (Add pathways and boss rooms)
(You have parts of areas in dungeons blocked off already which you could use for raid only content)

You can make all dungeons raids but please have two versions of the dungeon.

One normal exploring dungeon for all players to enter. (What its currectly is)

And.

One Raid dungeon with blocked and new pathways and adjustment on enemy level.

Another way to do it is add Add-On Raid only content to dungeons to contune going deeper within a dungeon.

Add in new methods to enter and have access raids.
Collect items within the same dungeon to have access or enter the raid.
Add in a Chocobo mount raid where its important to keep on your chocobo and evade enemies.

This is all shades of gray people.
