There's a Correct Target in D&D Combat
Although this is targeting 5e it applies to almost all ttrpgs. I couldn't help but think about how this could improve Mighty Deed of Arms.
Even my veteran DCC players struggle to use them effectively, much less theatrically. The comment about the completely open problem space really struck me as a cause for why so many players have lack luster deeds, if any at all. If there isn't a immediate or obvious problem to solve (beyond he presence of hostile forces) the problem space is just too large and people blank. I am going to talk to my players about it and see if having them identify problems to solve during combat, even if its just as simple as affecting the action economy of the battle, increases the number and quality of deeds they come up with. Much like the thief in the video, having fighter identify a problem they like to solve during combat instead of a style might yield better results.
