Cryptos posts on the forums about a subject very near and dear to my heart: loot whining. It is one of my great flaws that whenever I get close to a boss that I know drops something I really want, I can't help but share my excitement with my fellow party members, and sometimes (more often then not, unfortunately for them) my guild members. I'm sorry to say that I'm the guy he's talking about-- I'm the guy that is about to fight Murmur telling the guild, "man I sure hope my pretty dress drops." And it's a sign of how amazing my guild really is that they put up with me talking about it all the time.
But then again, loot is basically why we play the game in the first place. Shouldn't I, and players like me, be able to share with our fellow players what loot we're going for, to let them in on the stuff we hope we get? Is it right for this GM to actually threaten to disenchant a piece of loot, just because someone says they want it?
I definitely agree it can go over the top-- one of my pet peeves is people who join a PUG and try to "reserve" not-yet-dropped items, especially when there are others in the party who would obviously roll on it. And for my part, I've already noticed that I should keep my loot hopes to myself-- my guild doesn't really care about me getting every little upgrade I want. But good loot is the reason why many of us play this game, and so it's only expected that we should be excited at the prospect of getting it, and want to share that with fellow players.
