Just came back a few weeks ago from a very long break (played at launch up to a bit after fractals were introduced, while Magic Find gear was still a thing...), so my stat is not very high (just reached ~60%).
Not to turn the knife in the wound Loke666, but I had looted Zap one my first playthrough (can't really remember where though), and last weekend I've looted Dusk from a green type container in the Silverwastes... I was really surprised to say the least..
Though I'm not sure I can craft 1 legendary, let alone 2.. so I'm debating selling them right now.. Since I main a Thief, Twighlight is of no real use, and Bolt, not too sure either (just got HoT/PoF, so I'm just discovering staff for now and loving it..).
