None of these modifiers bring anything positive whatsoever to the player experience - they don't provide challenge, they don't promote team play, they don't promote out of the box thinking, they're simply annoying nonsense that nobody asked for, that suck any fun out of running strikes.
I honestly wonder if any of these things are play-tested before being put in the game with the player experience in mind. Someone needs to have asked, "Is running over an ammo brick and immediately dying going to be fun?" or "Is standing in a rift but also having your health chipped away by this modifier going to be fun?" The answer is no, not at all.
Do us all a favour and patch them out asap and forget they were ever a thing.
