There are dungeons where you die as part of the mechanic, the game treats it as a real death as you unlock the tutorial text for death then as some solo no death attempt players found out.

But yeah, this game isn't made for it. You know why? Because you have to pull like 5 mobs 8 level above you to actually die after a minute. There is barely any danger in open world FF14. WoW is much more fun in that regard.
