Funcom, since you’re currently expanding the area south of this DLC’s map, here’s my idea on where the new biomes should be placed. Instead of reworking the southern coastline, have all three biomes (Savanna, Ashland, and Floodland) be located on an island chain below Siptah itself. Ways a player could reach these biomes is either by swimming across the vast ocean, or using a raft to fast travel (like you did with the Sunken City dungeon).
I agree with this idea. Multiple islands is something that the Exiled Lands touches on, but not fully exploits the mechanic. I would like to add moving boats though…that would be cool!
