I got my Gjallarhorn early in my guardian's story. I bought it from xúr the one and only time he has ever sold it, at the time looking for any exotic to add to my arsenal. After upgrading it, I expected all the other exotics to earn the term exotic as Gjallarhorn did, and still does, just to less of a degree. Few weapons have any right to be called exotic (ice breaker, thorn, last word, and a few others excluded). So for those of you who are so upset by this change, don't be. Gjallarhorn was what an exotic should have been, it just cast too big of a shadow over the other exotics. Those out there that have this truly exotic gun, rest assured your companion is still as faithful as ever. Just packing a little less of a punch.
And as for the elitist scum that rule over the destiny forums, Fûçk yourselves.
