One Blue Per Run, Not Stated In Advance

Ah, here's a good one, with important contributors:

1. Original Poster (of course)
2. Guildmaster of "greedy" person in question
3. "Greedy" person in question
4. Members of the peanut gallery pitching in

The story?

PuG of 70s heads into Black Morass and loot rules don't seem to be discussed up front.

Blue BOE bow drops, Hunter "Need"s as an upgrade.

Blue Trinket drops later on, party leader tells Hunter, "pass on this one, you already won a blue". Hunter rolls "Need" as an upgrade and wins the trinket.

Party leader comes to forums and posts his tale of woe.

Guildmaster of Hunter apologizes for Hunter's behavior and boots him from the guild.

Hunter comes onto the forums to join in on the discussion, full of bile and hate.

Check out the full thread here.

So, what do you think? Is the "you've already gotten a blue this round, pass" rule becoming something of a standard in PuGs, or was the Original Poster way off base?
