There should be a rule, that there can not be any game rule violations. When my friend heard about speedruning a battle as fast as possible, he came up with an idea of a battle where enemies are convinced to self-destruct or get destroyed as fast as possible (for example - time a battle with 13 other people who you talk with, get into that battle where all your enemies are your people, ask them to drown themselves). since that is obviously not fair to people who don`t want to violate any rules.
