Over yonder Lawful Indifferent way, cousin N. Wright has a thing or two to say about wizards with swords.
I like his post because it highlights the game (in this case, D&D) as a toolkit for imagination (my words, mind you), and it also gets me thinking -- why shouldn't wizards get to have swords?
The general consensus is that wizards can't have swords because they already have spells. Okay; I can respect that. But then I think about this:
Wizards suck at fighting anyway.
So what's the harm?
