Magic Vs AC is Very Poor Reasoning

[GMforPowergamers]

I like the simplicity and the ease in play. I do think some spells need some modfieres (like the shocking grasp advantage vs metal armor)

If they're going to have 6 different saving throws based on ability scores, then they could just as readily have 6 different defenses based on ability scores. They should be just 10+ability mod.

Here are some fresh ways to look at some old spells. Notice the attack rolls.

The wizard here can choose to attack different defenses in order to exploit the weaknesses of his enemies.

Magic Missile
evocation/class lvl 1/at-will/ranged 6/12/int vs dex/You shoot sling beads, daggers or darts doing 1[w]+int mod+1d4 force damage.

Enchant Weapon
evocation/class lvl 2/at-will/int vs ac/You strike with your force aura staff, dagger or wand doing 1[w]+int mod+1d4 force damage.

Force Orb
evocation/class lvl 3/encounter/ranged 6/12 burst 2/int vs dex/You shoot beads, daggers or darts that explode doing 1[w]+int mod+1d4 force damage.

Pressure Blood
evocation/class lvl 4/encounter/ranged 6/12/int vs int/You skyrocket your enemy's blood pressure causing 1d8+int mod force damage.

Please, never, no; otherwise we get the middleman we didn't need.
