Artifacts have danger levels just like other items. If you hit these surges in very low DL areas (PC, DD, UD), then you're pretty much going to end up with Long Sting, Black Tome, scorched spear, rune covered sling. There might be one or two other very low DL ones... don't recall. So it's a bit of bad luck hitting the same one four times running, but the odds of getting something good from a low DL surge is piss-poor anyway.
Hoping to win with every class, doomed. Archer, Barbarian, Bard, Beastfighter, Druid, Elementalist, Farmer, Fighter, Monk, and ULE Priest down.
