If dual-wielding was a thing then they would probably solve it with the Stance System.
left-stance = use left weapon, right stance = use right weapon.
Pros:
-1h weapons are currently divided into short-spear, sword, axe, mace. They have different properties in combat making it useful to have access to both. Swing at a knight with the mace, swing as peasants with the sword.
-looks cool AF
Cons:
- Must rework weapon selection mechanic
- Stance system is honestly really unintuitive and it wouldn't be a clean implementation
