Tabletop talky
Like I definitely want there to be four things to consider:
2h and light weapons function the same as the size system - each size up increases damage by 2 but reduces attack by 1. Harder to hit things but when you do you get extra damage.
I also want there to be a concept of modifiers a weapon grants you for style- a dagger increases your initiative for example, because it's easier to draw and wield though it's less effective at combat than other weapons

So those modifiers are size, initiative, attack, and damage. I have a concept of balancing the latter 3 around a total 1 point bonus between each of the categories added together, and specialized weapons to do certain things (like a whip) are balanced around 0 but give you options in combat
