see the Moogle's Law thread, I know there's an entry for "the NM You've been camping for 8+ hours without a Spawn is guaranteed to spawn immediately after you have to log to tend to real life".

Oh, and on the subject of teamwork, I was in a party camping Okupyete or whatever its name is; half the pt just went AFK. after 2 spawn cycles with no activity from them, the other 2 and myself dropped and formed a new party (and eventually inviting 2 new people on the same trial); we got kill about 110 minutes later, the AFK trio still not so much as twitching. The next day I log on to have a message flame from the original party leader (who went AFK). Was I outta line for replying with "shouldn't have been napping numbnuts!"?
