I think trying to take on over-leveled fiends needs to have a line drawn to it.

XI was pretty much ~10 levels depending on what kind of monster it was, beyond that it was hard to heal the tank before they were snapped in twain.

This right here.

As a PLD in XIV, I solo train against level 59 Amal'ja with varying degrees of difficulty. PLD + WHM can EASILY duo level 60 mobs, and a I have no doubt that a full party could probably take up to level 65. At a certain point, the damage your tank receives will outdo the amount your healer can cure.

The only reason people don't do it is because it isn't practical.

(Disclaimer: I say mobs, but this example specifically uses Amal'jaa. Different monsters have different degrees of difficulty, even if they are of identical level.)
