Mages don't care for stamina, and nonmages don't care for magicka. Fortify attribute is also plentiful enough that you never really need to worry about investing deeply into any stat but your "main" since you can cover up to a reasonable amount with enchantments.
But in a well-designed system, every character should want every stat to some degree. You should never be able to simply dump the other stats without severe consequences - Those consequences should be sorely felt, rather than glossed over with sufficient gear.
Strength = Carrying/equipment capacity (which should be important, with maneuverability being dependent on how much you're carrying as a proportion of your limit), Weapon damage (melee and ranged)
Endurance = Non-mental damage reduction, health, resistance to physical ailments
Dexterity = Perception, hit rates, Critical hit chance/effectiveness
Agility = Dodge value, speed, physical maneuverability (jump distance, aerial control etc)
Intelligence = Spell effectiveness, knowledge, Ability to learn new skills (martial and magical) and to craft items(such as potions), XP gain
Willpower = Spell capacity, Resistance to magical effects and mental damage, Persuasiveness, Ability to command companions
Merge Willpower into INT, Dexterity into AGI, and Endurance into STR for the simplified version. This is of important for ensuring that all characters will want every stat in some amount, but if you're desperate to let people play as glass cannons or immovable objects purely from stat selection (rather than specific gear effects) then they can be split at the cost of losing some of the system's elegance and intent - it's easier for characters to simply dump certain stats.
