Personally the purple to blue was disappointing. But a lot of is had been screwed since the update. I have only received on purple drop on the day of the update since then I haven't gotten one single drop or even a legendary weapon I don't want for weeks now while my group gets guns all the time. Ps I'm a daily player and I beat the cruxible and weekly nightfall my group gets guns I get shards and I don't have anymore guns to even use them.
