With 7.2 Blizzard announced that you will have a higher chance on legendarys with another spec if you havent gotten 2 eligable legendarys for that spec (including sephuz, prydaz).
The real question here is does this mean that every spec has its own bad luck protection or do i have to fear that my bad luck protection for my 1st spec is gone if i roll on a 2nd spec and get a legendary?
That would make the hole system kind of pointless. I remember a blue post where they said theyll look into it because they werent sure if that would be the case but i didnt hear any further information on that problem.
