Is the simple fact that you also do bonus damage to other players who are also using Iron Burden. In this scenario, you and another play are in a duel, but you both have Iron Burden on. You can: 1 shot body shot kill with a high impact sniper 1 shot headshot kill with a Le Monarch plus one or two ticks of poisen damage Literally every pulse rifle will kill you in a burst or a half burst less Shotguns kill you from a further range Fusion rifles will also destroy you much easier Forget fighting a handcannon. 110s are useful since you can 2 tap another burden user. Enjoy dying to explosives like it's D1. And many more! I don't see why this wasn't detected much sooner? Like, did they never conceive of the possibility of two burden users going up against each other? Well, RIP.
