I'm actually very surprised by how against the idea of "golf-bag fighter" is in this community. I thought that was the default of the fighter anyways.
You keep a greatsword for maximum damage, a longsword and shield if your goal is to have extra AC, a bow/xbow for ranged situations, a lance (if you have a reliable mount), a net because why not, and a few holy waters, acids, and alchemist's fires.
Having even more weapons with even more unique properties and uses really builds into the fantasy I have of "general master of weapons."
