Thinking about making a change to how the spell Magic Weapon (and related spells) work. Instead of affecting the object alone, the spell instead affects a specific wielder. Any weapons they wield for the duration gain the benefit- any weapons that leave their possession lose the benefit by the end of the round as the magical energy "bleeds off."
The goal is to help dual weapon users and thrown weapon users who want to make full attack actions, as well as switch-hitters. I've rarely seen Magic Weapon or GMW used unless the party is stripped of gear, but with this in place, maybe that would change a little.
