One of my guildmates ninja'd the Large Satchel of Spoils from the Obsidian Sanctum the other day. Technically, it was his run, he organized it, and he was Master Looter. Because it was his run, you could argue, he could do anything with the loot. But that's just ninja talk. The truth of the matter is, my guildmate had no manners. I mean, even fish have manners.
This is an MMO, the central letter there standing for multi-player. This means we play with other people, real people. Real people we need to treat with a basic sense of courtesy. That's one of the tricky things about that little fiasco -- we know our guildie in real life. He's a real person, an affable big fella my wife has described as a teddy bear. The problem is that in the game, 'bear' isn't the four-letter word to describe him. The satchel was just his largest haul, but he's been known to nick the occasional Abyss Crystal from a heroic run.
