lul follower can also proc legendary.This is gonna be epic.

This part of the changelog intrigued me.

I think that some legendary only drops on specific place.
I always thought this was the case with Spectrum, Rakanishu's Blade, Leoric's Crown, etc.
Spectrum probably only drops in Pony Level, and Leoric's Crown drops in Leorics place.

Now get this.There is ONE legendary that hasnt been found yet.(excluding the pofessional russian set of course)
The said item is Band of Untold Secrets.

The flavor text:
"In certain light the intricate runes of a long forgotten language can be made out upon the surface of this ring."

So, the question is was the ring accidentally excluded from current client?
Or the whole population of earth that play diablo 3 hasnt found the legendary in that specific place yet?
Or is it a "quest" item related to The Black Rock Ledgers?
