We don't know all 18 skills, so one might have perks associated with speed. Also, upon every level up, you can upgrade health/magicka/stamina. I'm sure the more you raise stamina the longer/faster you can run. The more you raise health the more you can carry. Sounds great to me. Thank you Beth.
Presuming that's the case, that represents a narrowing of options.
For instance, in Oblivion, it's possible, by pouring increases into endurance and ignoring strength, to create a character who's physically weak but resilient - the equivalent of a small, wiry but tough-as-nails person - the sort of person who couldn't bench press the bar by itself, much less with weights on it, but who can take a beating and keep going. That sort of person, if the system you mention here is the one that will be used, will be impossible to create in the game. Characters will be stuck either being strong in all regards or in none - simple and inadequate binary distinction.
I can't see how that's a net gain.
Wait, she starts out the same but end differently...
...
I don't see the problem here...
How can she "end differently?"
There are only a limited number of perks. My male Nord heavy armor tank, at the first opportunity, takes the perk best suited for a heavy armor tank. My female Dunmer heavy armor tank, at the first opportunity, takes the perk best suited for a heavy armor tank. They're still identical. At each appropriate point, they each take the perk best suited for a heavy armor tank, and they end up staying identical throughout the game (again, except for the briasts, which really doesn't count as sufficient individualisation).
