The best etiquette would be to wait for your opponent to finish clearing the enemies and then give them a waggle of the shield or a bow to let them know you’re ready to duel. Then chugging wouldn’t be allowed, but if someone rocks up and starts being a dick then it’s go time and you can do whatever you want. This guy was clearly being a dick and wanted an easy kill with his twatty Claymore.
The use of the trees was a genius piece of improvisation (?), but why weren't you attacking much/at all.
