Thorn was nerfed because of full teams of Thorn users in Trials. Bungie said so themselves. I've never seen one weapon proliferate a battlefield in normal Crucible or IB. It's always a wide range flashing by when dying. Trials is the place where people die to one weapon an entire match and crap their pants over it. BTW agree Bungie's "testing" is worthless. How can you balance anything in sterile test environments and why adjust everything at once instead of one thing at a time?
