The new archeology filter is definitely working - I've cleared every NE unique artifact there is and as a result, I've had runs of a dozen or more dig sites in Uld, resulting in two or three trash artifacts before leaving the zone. Despite these impressive runs and shear quantity of combines, I've only gotten one unique so far, the ring - no sign of the other items, not even the pet or the toy that summons scarabs.
The result is that these rather frequent streaks of TV digs make the whole prospect of finding these uniques seem even more daunting then ever.
I'll keep on hacking away at it none-the-less though - something to do while watching Numbers I guess.
