Personally, I think Full Auto is a useless perk on anything that isn't a high ROF Scout. It isn't useless, but I'd much rather swap it out with a more useful perk like Crowd Control. The other day I got a Cryptic Dragon from Crucible with Crowd Control, Firefly, Hand Laid Stock, AND, the Red-Dot OES sight, the same one Vision of Confluence has. It's an absolute monster and just replaced my Hung Jury SR4.
