In a game I used to write for, we used to have community wide testing directly in the game on certain days. This gave a much needed broader sample base. The next day, all changes were reverted and feedback was collected. Sometimes we made some big, silly, crazy overpowered changes just for fun as well.
Since balance changes are all happening serverside and no client update is needed, what does everyone think of having a day like this once a week/bi-weekly/monthly?
