Would it make sense to count a steel shield as a bonus to AC against Shocking Grasp? Scorching ray? Ray of Frost? Any energy damage?
Metal is a great conductor and since yuor arm is in contact with the shield (or hand and arm) then the "effect" of the spell should penetrate shouldn't it?
In order to come up with a means of counting a shield for AC bonus against touch attacks all of these type of conditions need to be addressed. Which would, IMO, lead to a reall large and complex house-rule to address the issue - hence the RAW is best and simpliest for the D&D abstract combat system.
