[Spoiler] Isn't Dark Knight using Akasa ?

I don't really understand the backlash against dynamis, but maybe it's the physics analogy, or that even in the fantasy I read with hard magic systems (Brandon Sanderson comes to mind), they don't tie every single magical element to one system or force, even if that's the one that gets the most detail- but having everything in XIV being handwaved as 'aether' was deeply unsatisfying and came across as lackluster undeveloped writing. Having a second named magical force that operates in ways that can be both opposing and complimentary, and isn't a complete handwave mystery but has some room for the writers to flesh it out - and that it is regulated to being weaker except in very specific circumstances- only comes across as a bonus to me. Sure, I understand the fear that everything and every enemy going forward is going to be explained via dynamis instead of aether because here's our new hot plot macguffin - but it's yet to be a factor in the Pandaemonion raids, and it feels like a useful additive retcon instead of subtractive.

It certainly made Omega Raid less cheesy.

When it comes to Lore some people just are very attached to the old ways. Adding something new, even if it IS an additive retcon and can fit into the lore, is still a retcon to them. So, if they've been told for 8 years that everything we do is through aether, then by god, that's it. Nothing else. It breaks their head canon and some people don't adapt to it too well. Trust me, it took me some time to grasp dynamis as well, but the more I thought about it, the more I felt it made sense and could fit very well into the lore and I'm excited to see it explored more in the future. We find new discoveries of how things work every day in real life, so it makes sense that people can find it in a fantasy world as well.

Any long running story is going to have some inconsistencies here and there. FFXIV has kept those to a minimum in my opinion, though some people treat this stuff like WoW levels of retcon. I feel as a society we tend to overanalyze everything these days. People freak out if everything isn't spelled out for them in movies, for example, and expect it all the make perfectly logical sense and can't just enjoy stories for what they are. As a scientifically, logically minded person myself, there are times I get frustrated at the stupidity of certain things I've watched. But I've learned how to turn my brain off during those moments and just enjoy the spectacle.

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.
