Upsetting the WIZARD applecart,... maybe?

[Jim Kane]

As magic is governed by IQ, why are Wizards rolling to cast spells against their DX like a fighter in a Melee, and not against their IQ stat?

Does it not stand to reason that since magic is a thing of mental concentration and magical knowledge which determines the ability of a wizard to reliably manifest his will from his thought-forms - as it is the power of the mind that determines the successful casting of a spell, and not the physical adroitness of a character - so that 3d6 vs IQ should logically be the basic roll for successful spell-casting; with the Missile and Thrown Spells (at a target hex), requiring a subsequent 3d6 vs DX to hit their target-at-distance.

Except in cases of Summoning and Creation spells, should not then the proper sequence be: 1) roll 3d6 vs IQ to successfully cast, and then, 2) roll 3d6 vs DX to project and successfully hit a target?

Furthermore, why are wizards not powering their spells by expending IQ Fatigue; as opposed to ST Fatigue?

That concept would certainly eliminate the complaints about the high-ST "Wizard Tank" characters who develop over time.

Where am I off-base here?
