Well, the rev6 spawn list is just a guess, based on earlier spawn times. They may have still 2 hours till they spawn on rev6, but it will actually spawn earlier. It's nothing but just a bunch of numbers which may be (rarely) right.
As for the high levels hunting uniques. If Joymax would care about their customers they would implant a system where someone, who got a Uruchi kill in the last 48 hours for example... it would just ignore him. Just as if he wouldn't be there. Or just make him unable to deal ANY damage to it. But that are just dreams. Silkroad and the players that play it are mostly (most, but not all) selfish bitches. All they want is that their name appears on the screen. But the more uniques they kill, the more people will hate them. And they (100 kills plx) will ENJOY to see people blaiming them for their unique kill amount. Or they just want a huge collection of videos (like
this idiot).
And one last thing. These forums don't allow bots/loaders, right? Then it should NOT be discussed about rev6 either. All the information they collect if gathered by players who use their bot. If you don't believe me, ask their administrators. They will confirm it.
