As a physician, I've noticed there's been quite a lack of treatment opportunities of late.
Likewise, I've noticed over the years that many characters will spar with their normal weapons, rather than buy practice weapons from woodworkers or the NPC shop.
To encourage both, I'd like to put forward the suggestion that safe attack could give a chance of injury when used with a real weapon.
The chance could start out high, and decrease with the skill level in that weapon- that is to say, someone inept at using a sword would have a high chance of hurting someone with it, while a grandmaster has the control to (almost?) never injure.
Edit: Another thought I just had this morning, perhaps using a real weapon under this system could offer a bonus to pool, as a sort of reward for the risk, and thus help with point 1.
