I haven't experienced this modifier as I quit before it was implemented so I can't reasonably comment on such, but it does sound horrible from the explanations and complaints. In all honesty, Bungie has been going overtime making annoying modifiers that are automatically applied to any activity, despite their advertised Portal being able to choose which modifiers you have on. Of course, there always has to be some fine print where Bungie wants to irritate their players rather than making the game enjoyable unless the player specifically chooses to add some extra "training weights."
