One-Handed Caster Weapons and Shields?

[Giantbane]

Simply make weapon and shield in one item, like tank armour that cannot equip head gear.
Then solves everything, it will be one single item, but appears as 2 pieces on you when equipped. ^^;

This would work well for casters because they only have one type of shield.

PLD might have some trouble with this since they have 3 types of available shields.
