Well, my friend and I decided to do a test, I ran Nightstalker and he used Gunslinger and Celestial Nighthawk. Tethering Randall took him down to half health instantly (somehow?) and naturally, Golden Gun absolutely obliterated him, therfore, Randall The Vandal, is no match for supers, post patch 2.3
Edit: uhhh. So Golden Gun without tether OR Celestial Nighthawk absolutely melts him...
