In addition to what has been stated above, the idea that he is every WoL's mirror also comes with the perhaps unintentional implication that if we don’t like this analogy, we have probably not entirely understood the story or we are trying to deny that part.
That’s why I strongly disagree with this point.

Whether he is deeper than other villains, is very subjective in my eyes. There’s no right or wrong here. But the depth you appreciate in Zenos I see more in other villains.
And I think most people understand what the game tries to do, it’s just not working for some of them.
I understand that the game wants to set him up as our counterpart in battle. The fact that we almost die as equals makes it crystal clear.
But for me the
intention alone to tell this story doesn’t automatically make it a good story.
The same goes for his background: You are probably completely right about his background story.
But for my personal enjoyment of a character, it’s not just enough for me to know this information. I would like for it to be presented compellingly so that I can experience it within the story.
Good writing is very subjective. I’m completely aware of that. But for me, a story is first and foremost a "live" experience. It’s not just the “what”, it’s also the “how”. It’s not just a summary but a means to experience the events first hand as if you were right in the middle of them.
How a certain plot-point or a certain character are written matters a lot for me to “take the intention of the writers seriously” so to speak because they found a credible way to integrate it into the experience, i.e., the story.
A good example is Urianger, imo: Up to ShB he was very bland, in my eyes. When he loses Moenbryda in ARR it was kind of underwhelming because I didn’t feel enough for him or how his loss was presented to be really affected by it. The story hadn’t turned his character and his emotions into a compelling experience.
Now in EW this is completely different. The scene where he meets Moenbryda’s parents is probably my favourite scene in the whole expansion because it is so well-crafted.
The
topic is still completely
the same. But the
delivery is
entirely different. This leads to a
completely different experience and for me to a completely different level of depth.
So,
knowing that Zenos probably has a certain background does nothing for me to appreciate his character because for me the
experience I have with him in the game is exactly as @StriderShinryu describes.
Whenever I actually meet him, I feel like I’m presented with the narrative of what for me is not the expression of a deeply broken character (although that may be the intention) but the shallow and one-dimensional depiction of a motive (embodiment of ultimate battle lust, alleged mirror to the WoL) in the body of a perpetually bored, uninspiring and sometimes clownishly arrogant shell instead of a fully fleshed-out person.
But again,
that is just how I perceive his writing. My point is
not that I think this opinion is objective or that people who feel differently about his writing are in turn wrong.
I just try to argue against this idea that the fanbase who dislikes him takes him at face value and that he is
objectively a good mirror for
The WoL of FF14.
For example, this is a sentiment I heavily disagree with:
I very much think that they are going to point out that our character would have wound up exactly like Zenos if it wasn't for the people around us.
This is a big blanket statement in my eyes that tries to press
every person’s WoL into a narrow mold and fails to account for the big difference personality makes in this scenario.
I do not think at all that every person would have ended up like Zenos. Some definitely might have. But other people might have such a different approach to life, a different approach to battle even, that it leads them into a different direction than becoming Zenos 2.0.
Zenos externalises his problems by becoming aggressive and violent (and very, very bored).
Other people might internalise this loneliness and become depressed (but not violent). Some might actually start to resent fighting because they are repeatedly sent on these dangerous missions but they are all alone. Maybe they would give up on being a hero and an adventurer all together. Some might be able to shoulder it and just keep going.
I think there are a myriad of ways to react to this situation just as in real life different people can react very differently to the same challenges and problems.
(Also, ironically the game actually gives us an explanation why we are a hero in the first place. We are a part of Azem and the defining trait of Azem is to always want to help and solve others’ problems.
Acc. to the game you help precisely because of the well-being of others and not because you hunt for the next battle.
This is also an interpretation that the game forces on
The WoL so I completely understand if people are annoyed by it. If you are not the type of person that would throw themselves into a volcano to help others then this characterisation feels very superimposed, as well.)
Lasty, I think that Zenos does not just embody “the darkness” within us as other people have suggested before. Zenos has very
specific dark traits that do not necessarily correspond to the dark traits and aspects of just any other person.
Even when I envision my char as the edgiest, most demonic, annoying anti-hero I still feel as if what makes her “dark” has nothing to do with what Zenos embodies, hence he cannot act as a mirror for it. He is completely unrelated to my character’s particular “darkness”.

Garlean trained from birth > Aether powered swords > Resonant > Shinryu > Ascian powers > Souls of the slain > The Mothercrystal > Dynamis dimension.
In itself I agree with this scaling of his power. But considering Dynamis runs on thoughts and emotions I would argue that we should have an intense emotional high after defeating one of the most powerful beings in existence (how is that for battle lust), saving the universe (and particularly our friends and loved ones) and even freeing Meteion. So, personally I would still feel like the Dynamis power of our own state of mind (in addition to our absurdly high normal power level) should be able to blast Zenos into the horizon. But that’s just my interpretation.
(Also, I would say in this case Shinryu and the Mothercrystal don’t constitute two different sources of power. Rather, Zenos uses the Mothercrystal to summon Shinryu. So, I think the primal is the manifestation of the Mothercrystal’s power, not an extra power boost on top of the crystal.)
I think the powercreep of our character is a serious problem and I know the writer will eventually just have to downgrade us “by force”/for the sake of convenience again because otherwise the story can’t really continue. So, in itself I understand that we also need “normal” foes who present a challenge to us.
But for my taste the timing was not very good. The crass juxtaposition, this direct sequence of events with completely different tones in THE most important moment of Endwalker made it feel so misplaced for me.
Regardless whether it is Zenos or another character, I wish they would have challenged our WoL with a “normal” foe before the finale and played a lot more on Dynamis during the last fight. I wish they would have showed some epic large-scale “the whole planet prays and is with us” (not just the scions) scene before the Endsinger fight to really emphasise that WE are not that strong but that we are just channeling the hopes, prayers and the will to live of the entire planet.
