But doesn't a sword and board spam hits too? I don't understand this logic. As a Mage you have way more options than a warrior. You have illusion, conjure, and destruction to manage while kiting. And in destruction you can choose AOE or stagger spells, change spells depending on enemy resistance, change spells by damage bonus (ie lightning against mages), defensive cloaks, etc.
I find my mage much more varied and challenging and fun than my warrior, which got so boring by lvl 35.
Sword and board characters can be built up to use illusion, conjuration, etc. as well, so if you just look at the act of dealing damage, Destruction basically has left hand, right hand, and dual cast, of which you're probably only going to be using dual cast later in the game. It has a lot of different spells, but by the end of the game the only ones that deal sufficient damage are the three incinerate level spells, which leaves a choice between three elemental damage types, all of which are very similar in terms of the mechanics of the attack. Sword and shield on the other hand has bash, power bash, shield charge, block, attack, standing power attack, running power attack, side power attack, backing power attack, all of which have their uses and make for some interesting options in combat.
I did have a ton of fun playing as an archer, and that only has a single kind of attack, but you can get its damage up higher than destruction, and also have sneak attacks, so you feel very powerful, while with destruction, your enemies seem weak due to the dual cast stagger effect, but you seem weak as well since it still takes you a lot of hits to kill anything.
