Skyrim is dumbed down and that's what I like about it, plus I liked the perks, I know not everybody will but I really did. It was something I loved in Fallout as well.
See, it's all about context and the overall experience for me even the UI matters in this regard, let alone the layout and function of stats/skilles. I liked the Perk system in Fallout because I felt like it made sense for Fallout to be that way.
Where as, I don't like that in Elder Scrolls because that's not what Elder Scrolls is to me, so them dumbing it down in different ways removes different aspects as to why I liked that series in the first place, mechanically what they did is fine, just put it in another series.
I played a whole bunch of different RPGs growing up, And I found a lot of them to be pretty simple, most FF games don't have much depth in character building and stats, that's fine.
I get bored of games that are grindy in the sense of "You need x amount of XP to level" but I love it when my character is progressing by doing different actions to level up parts of themselves that make up a greater benefit in the long run. Morrowind had 27 different skills on top of the regular attributes, I love that, because that was way more indepth and different to anything I had played before then, and it took me 2 days to work out how to even start leveling, that was a wonderful experience, exploring and figuring that out, chipping away my character, exploring the land and so on.
I'm not going to argue it's practicality because it's not really practical for a game to be that way in the sense of marketing and selling, but I thought the way everything worked was great because it was so unlike anything else I had seen or played at the time.
That's what Elder Scrolls is to me, so while I really like Skyrim's Perk system, I don't want it in a series that didn't work that way.
Sure games and genres and individual series need to evolve and progress and so on, but that is not the way to do it in my opinion, I believe there are plenty of other ways to refine a series without changing it into a different series that is a vague shell of what it was.
But you know, I'm not a business man, nor am I a game developer, but I know what I like, and when I really like a game/series, it's not for a singular reason, it's the entirety of every little and normally insignificant thing in the context of that game or that series that make up an overall experience that is unique.
I suppose I appreciate games differently to a lot of people, oh well it is what it is.
