Doesn't answer my question. Why not both? It's a video game, so if people want 'nonrealistic' weapons, they have as much right to have them as those who want realistic weapons.
That's doable only for standard, non-unique weapons, and who uses those? One of the problems is that the most powerful weapons tend to have the silliest designs. DAO was somewhat reasonable about it, even though the weapon sizes were outrageous as well, but DA2 pulled all the stops and went off into the land of nonsense.
A functionality like the DAO mod "The Winter Forge" provided for enchanted weapons would be nice: among other things like creating new enchantments, it lets you transfer enchantments from one item to another. I never play without it these days.
