Since we do know that we have the option to increase our Health, Magicka or Fatigue Stamina with every level instead of attributes, Endurance, Intelligence and the way Stamina is being calculated are obviously being totally reworked if not downright removed along with the other attributes. Also, since the Major/Minor skill system is being reworked to allow for a more organic character creation which doesn't totally [censored] us over should we choose to respecialize, I wouldn't be surprised if we didn't get to choose our character defining Attributes right away.
All Bethesda games probably including Daggerfall had a problem with health gain at high levels. You get to much health as you gain health every time you level up while the enemies does not increase damage enough to balance it. As your endurance raises the health gain at high levels increase.
Quite possible to finish Oblivion with 30 in endurance if you are an archer or mage, a little harder at medium level but no problem at high level.
Fallout also had this problem, ended up having to tank for stupid Clover against albino radscorpions as she died far easier even if she had better armor rating than me. Yes my endurance was low and no more health perks.
Linking health directly to endurance and not to level would avoid giving the character to much health at high level while still letting the barbarian take more damage than a glass cannon mage.
Without attributes you would had to link health to blade and blunt skills who is stupid.
if only linked to level the mage and barbarian would have identical health who is more stupid.
