This is a system that is meant to be 100% upside, so anyone worried about getting screwed by a reroll shouldn’t worry. When I think about how far HS has come in this area, it’s pretty crazy. I used to only have a small fraction of every set, but now with this reroll thing, plus the (much, much more significant no duplicate protection in packs), March of the Lich King is the first set I’ve completed.

(Side note: what’s the final word on how we are collectively abbreviating this set’s name ? MLK is already taken…)

I did it, rerolled one of the signature legendaries from the reward track and got a duplicate legendary instead (Frostmourne :S)., 

 This happened though because it will only reroll from the same set. Path of Arthas is its own set, so there were only three options in the reroll for you, and if you purchased PoA, you would have had them all and therefore have been guaranteed a duplicate.

 Exactly. But the duplicate card cannot be dusted, right? It's just an extra copy.

 The extra copy should be dustable as far as I know
