You've played with a lot of people for a long time. Particularly your wife if memory serves.
Just as an example, a theory if you will, has your wife ever in the last, what? Twenty years? Has she ever declared something similar to jumping from a chandelier with a divebomb attack and gave a recommendation on the rules she is thinking that would call for, that you agreed with?
For example, if a Chandelier is 20 ft up, I could see doing an acrobatics check, dealing likely an extra 2d6 damage from the fall, while the player takes a d6 from the impact.
You might disagree, propose something else, but here is the kicker. If we can reach an agreement on what is reasonable, then we don't need a referee or a "final authority" to rubber stamp it.
That is what
@Campbell is talking about. If people can propose ideas, and in a quick discussion come to something they both agree is a reasonable way to work that idea, then you don't need a "Final Authority" to approve of it. You've done the work already.
