I think an update to the Looting section is necessary in the ddowiki to include that information.
Perhaps even a "Loot Gem" entry to further help clarify this.
if i knew where the dev could be quoted from i'd make a thread in the new player section right away.
Actually, I find the problem is more of people not wanting to join random LFMs as opposed to people not wanting to start groups.
1) There's already incentive to start groups: so that you can actually do the quests you want to do in a group. If there's already someone doing said quest who's spots aren't filled, then there's no issue of people not forming groups regardless.
2) People don't like to PuG (far as I can tell from forums). And from personal experience, it's hard to start a group for a quest which you don't have sufficient experience and/or capability in regardless. (I can almost guarantee that a wiz or sorc starting a titan raid run, who states in LFM that they can solo the green puzzle, will easily form a group. Especially if they've a monk/FvS in the group who can get the levers as well. Not imagine a non wiz/sorc/fvs/monk person who's just newly flagged for Titan raid. The odds of him/her forming a successful group drastically plummets.)
