If you've got a group which really enjoys tactical combat, and wants to WIN that combat rather than breezing through on DM fiat, then it's actually pretty nice to be able to step back and referee a conflict between two separate groups, both of whom are trying their best to beat the other.
It's not what I want every single game night, but it was interesting and fun as a sometimes food.
It's funny and also potentially useful. So it was humorous, but it was not just humor.
