I've always been amazed and amused at how from the beginning that XIV has worked to explain with in-game lore elements that I was willing to accept as genre or gameplay conventions, elements I was perfectly able to turn my brain off for, be it the Echo to explain wipes in dungeons, the various explanations for Extreme and Savage versions of fights, that at least some of the Duty Finder has canon moments, and now dynamis for some of the 'heroic willpower' like in Omega and at least partially or some of the Limit Breaks.
