Legendaries/sets I've found include:
1) A (terrible) weapon I sold for like 150k.
2) A lvl 47 monk weapon. It was decent on my alt, but almost immediately overshadowed.
3) Tal Rasha's Armor. Not great, but not horrible.
4) A low roll Lacuni Prowlers with a low dex roll as one of the mods, which I'm now currently using. Quite useful because they're the only source of IAS on bracers. As a plus, they also have move speed.
5) And today, one of the few actual useful weapons, a Three Hundredth Spear with max MF, (it's useful because it has magic find, not because it's a good weapon in of itself) at the end of a pony run, which is currently itself being used at the end of pony runs.
Though, as I said before, basically all set/legendary weapons and a large chunk of armor is pretty much worthless right now.
