I've only played a total of 14 hours, story, strikes, and bounty time included. I've completed my legendary set, save for the helmet as well, and have a full set of legendary weapons including the Exotic shotgun so I mean, it would seem that it's a bit quicker in comparison but I can't really be absolutely sure.

Saboteur-6 The shotgun gets whored quite a bit in Crucible, but Clash makes it a little less so since there are no objectives to be taken, so you can stay out in open space as much as you see fit. I think it's a bit of an issue though as well
