For RtwP games, I'd like to see more Tactics systems that DAO had. Being able to customize companion behavior to that degree really helped limit the amount of in-combat micromanaging I had to to.
This type of system would require a lot of adjustment since D&D has #/rest abilities and an action+bonus action per turn instead of DAO's cooldown abilities and a single action per round, but I think it still could be done.
The reason it works so well for DAO, is the fact that Bioware created their combat and skill system from the ground up, for RTwP.
Translating tabletop DnD rules of any edition just doesn't work well since in every version, there are mechanics that rely on a TB system to be implemented properly.
