Its simply false, all that crap rumors, to many jealous peple saying to much shit.
Yes there was some duped but thers plenty of honest loots and spreading all that shit info can only be based on jealousy ?
I myself have had dupes in inventory thou to no action of myself. it was a bug that occured somtimes i had at one time 8 sets of orange clothes and stuff, most dupes had tt 0 and couldnt be repaired.
It was MA´s decission to let all dupes ingame at the time be legit and let them be repairable.
Get over it and get done with
Back to question afaik the last drop was from warlock in the times when it was freespawning not far from pvp1 and i heard a guy looted 2 in one night but i have never seen screens. its likely end 2004 start 2005.
And yes im quite convinced that MA follows the principle of entropi and that if anymore uber items will ever be spawned it will be because they add to the numbers due to player count of because old/banned accounts are purged.
