The removal of the Nightfall buff actually allows more freedom of play. I no longer am forced into the Nightfall if I want to fully max my xp and rep gain. Class items now offer higher rep gain and you can earn rep in your chosen faction along with Vanguard/Crucible rep. Something not done before TTK. Greater freedom of play also goes into the removal of both elemental primary legendaries and year one weapons. Fatebringer, if you had it, was always the obvious choice for arc burn activities. VoC was generally the choice for solar burns. Why would you use anything else when those were the superior weapons. Now? Well now you actually have a choice. No need to put aside a favorite weapon just to use a vastly overpowered weapon for a burn activity. Relegating raids to the level they were intended for does not much help for freedom of choice. But really, how many MMOs constantly update old raids to still be on par with new ones?
