Recently I've been wondering if prepping has been hampering my GMing. I've been GMing for the past couple years, and I've found that I'm spending an increasing amount of time prepping. And while that pays off great for the content I do have prepped, I honestly feel less confident in my improv these days. This has led me to prep more to minimize improv, but now I'm thinking it's making my improv worse. Is there anything I can do to improve my improv specifically? Should I intentionally under-prep a little to exercise the skill?
