Make instanced/open world content for all groups, strive for accessibility and clear instructions and remember the different groups. Maintain the instanced contents ilvl for casuals. Create open world systems with long term progressive systems similar to Sky or Sea but not as long lasting for midcore and hardcore. Retain tight knit instances for midcore with group number and mechanic leniency, and keep pumping out the savage version for hardcore.

Here is a look at a type of different content.

You could possibly fit some of that into something equivalent to Deep Dungeon, however FFXIV will never have this on the open scale due to balance and cost issues. Non-instanced content creates an enormous load on servers. Larger ones simply wouldn't be capable of handling the influx of thousands of players in one play, alongside everything else that needs to load. Furthermore, public dungeons would devolve into zerg fests ala hunts presuming you mean players could simply run into them.
