Step 1.) Have a terrible internet connection, preferably via proxies of Mexican or Chinese origin. Step 2.) Use a shotgun. Step 3.) Be a Hunter, since all the other people using this technique use Hunters. Step 4.) Play Iron Banner. Your opponents won't be able to hit you, as you'll be flying all over the map, walking into walls only to whip 40ft in a different direction. Anyone who gets close to you will die to blasts from your shotgun that travelled through time, and any damage you would take—if they managed to actually hit you, that is—is nullified due to lag!
