Refusal to participate in the duty is considered griefing and can get you sent to GM jail: Do not do this.

Try to deal with the extra mobs to the best of your ability: If you survive the pull, you weren't pulling enough. If you wipe, you can blame the 'rusher' and dismiss them from the duty without any baggage.

Forcing a wipe in a situation that can be easily recovered just because you want to 'punish' someone is far and away more toxic than grabbing extra mobs because you think the party can handle it.
