I call the habit that people developed in Oblivion the "Major Is Minor" phenomenon.
I think that having just 10 skill-ups should denote a level-up, and then it tallys up the skills and ups their associated attributes at level-up. Then you choose which of the three vitals you boost (the quantity of which depends on associated attributes), and then you choose your perk, and then you're off to level-up again.
Instead of having major/minor/misc stat setup, you'd choose two specializations out of the Warrior/Mage/Thief triumvirate (or choose one twice), and those give skill advancement rate boosts (with "choose one twice" doubling the boost). Racial skill inclinations would also give skill advancement rate boosts too.
Actually, as far as we know (which is nothing regarding attributes) they could be in or hidden or out or entirely different. That's why the term "As far as we know" was used. Because we don't KNOW anything on them yet.
Anyways we DO know that there is no class choosing, level ups are still based on skill gains, and we get perks when we level up.
The term was followed up with a use of "they aren't there anymore", which by your own post you admit may not be true
The only thing I have seen is a lack of mention of them. The fact that numerical values denoting innate statistics of a character is a staple of the RPG genre means it could very well be an understood fact that they're there. However, some insist through some eleven-dimensional contortion of logic that their lack of mention means they don't exist; that absence of evidence is evidence of absence. Which aggravates me to no end when I see it asserted.
