In vanilla morrowind, sorcerer has got almost all magical skills as major, and also heavy armour, short blade stuff as minor, which baffles me a lot.

Is sorcerer a pure spell caster like Mage but only wearing heavy armour to get a good AR bonus? Or does it play like spellsword but with shortblade and marksman stuff?

If I play like a combat-mage, do I even need Destruction anymore as I get my dagger handy?And do I need to boost up my strength by training misc skills?

PS: Is it necessary to gain a 5x3 attribute boost by training misc skills hard per leveling?
