Will Relics create the same problems that they did in FFXI?

i think thats the key. having a piece of content that takes 5 or 6 hours of your day makes it inaccessible to most not in any part due to difficulty but simply due to time constraints.

What kind of Content requires 5-6 Hours in FFXIV a day? To make it even easier, which Content even requires 2 hours a day in FFXVI? No Content/Instance in FFXIV is forcing you to stay even 2 hours in the Game.
