Fixed. If your substantive point is that complexity is a matter of personal taste, you shouldn't embed your own preferences into your description of the issue.
Back when I was 18 or so, I liked complexity for its own sake too. I'm not really sure why. Possibly as a some sort of a geek status marker, possibly because I wasn't really a very analytic thinker then. A few decades later, and the complexity of a lot of game systems now strikes be as being, essentially, noise. For instance, when you master the D&D magic system you learn that a lot of the spells are outright worthless, half the rest are only rarely useful, and the useful stuff that's left over includes a lot of duplicate functionality, so the number of spells is a lot more than the number of actual abilities those spells give you.
When I was 18, 12 years ago I didn't even bother with complexity. And I can perfectly rationally explain why I like complexity IN STATS/ATTRIBUTES/whateveryouwanttocallit specifically. I hate complexity in strategy combat, like in Divinity, I HATE IT. Not everything I use as an argument is something I like, because I can perfectly separate what I like and what is good/well done.
So first your post was directed towards somethings I'm not. I' not young, I HATE difficulty, challenge and complexity in gameplay. HATE. I just don't play games with it. I didn't even play Disgaea just because it had different types of ground (squares your character stand into) and it was a factor in gameplay. That is how uch I hate complexity.
Then comes the problem of complexity for the sake of complexity that you are also so wrong it makes puppies die. I love complexity in status because of two things:
1. I am all about exotic and the more variation on stats the more I go away from traditiona useful builds. The best RPG I played, stats wise was an MMO, Trickster Online, it had 12 stats divided into 4 groups. I could do all kinds of builds.
2. It is not exotic for the sake of exoticness too. My tastes in real life are exotic and NEVER I found a simple game in which I could represent myself and all variations of myself (my characters). With stats, as many as possible, I can make "myselves" (lol), sometimes, perfectly, specially with mods. In Trickster I could control ASPD, damage, hit chance, critical chance all in separate stats, not just Dexterity like many RPG do. On top of that I could add all the equipment thing. But I'm also content with D&D 6 stats thing, not that bad and usually helps me since out of battle they represent a lot and help me even more to represent myself. In Inquisition it is 100% impossible to even start to represent myself. In fact I should give some random name to my character and name the armors and weapon I craft with my name since they are the only things you can customize (and it is kind of what I do like using my last name, its meaning and variations to name armors, addons and so on). It is ridiculous, I am my armor, the character itself is nothing but a generic ****. Also as I stated before your stats mean nothing regarding who you are, this **** is not for me (or anyone who like RPG). Sometimes I manage to represent myself with only 4 stats, but it is VERY rare. Usually 6 or more is gold. 4 sometimes is barely enough, most times insifficient. 3 or less is just never enough no matter what, even coupled with high equipment customization.
So yeah, I hate tactical combat and complexity in general but I accept it because it usually comes with my real need, a good stat system. I need it because no simples system gave me what I needed up until exactly now. Simples games work for people who want to take joy in playing thegame, I mean the actual playing, combat, puzzles, exploration, etc
People who's joy is only in making the character and creating thousands of builds (nwn2db.com for instance) will get nothing from a game like DAI. Nor did they get from DA2 that even having 6 stats had them simplified to optimize class hit/damage as Inquisition thus reducing the possibilities for people like me.
That's it. NOTHING related to what you thought I was talking about because it is nothing of complexity for the sake of complexity since I hate complexity except for the stats for reasons I specified above.
Edit: Also, functionality. This word is poison, hell, doom. I despise functionality more than anything in my life. Even in real life I hate how people let go of subjective and creative choices in favor functional, even when it means life or death. If my life was an RPG my enemy would be called Functionality. Things don't have to function, they have to represent you, no matter how useless they are (like most y builds are).
