Bravo, sir. I'm a nearly exclusive PvE player that went into IB on a whim this weekend. I faced plenty of Thorn users, and suffered plenty of that "unbearable" DoT burn. The weird thing is, I killed Thorn users more often than they killed me, and only rarely died to the DoT. Most of the time I was using unleveled hand cannons; sometimes I used an auto rifle. The majority of my deaths probably came from suicide shotgun charges, an unavoidable occurrence in a game that doesn't really punish death. The weapons don't need nerfs; the re-spawn timer just needs a buff. "It's not the gun in the hands, but the hands on the gun."
