This has always been in the game and being on power for an activity is “recommended” for a reason. The Dares thing was only of note because, iirc, you were spawned into an instance of Dares the moment you logged in and so naturally players would assume they should complete it. While base nightfalls are not particularly difficult, you can certainly imagine getting a 1920 gamer in your Tomb of Elders run might negatively impact your experience (and the total loot you get at the end) and therefore it is a logical quality control measure to separate lower power players in matchmaking pools for some activities. Nothing is forcing the new player into this activity and they have the agency to leave at any point. It’d be like arguing because a new player sees a pinnacle drop behind a raid and can load in, then they should be able to complete it solo and under power. Clearly it is irrational to craft the game under the assumption that new players can’t read or decide how to use their time as they see fit. If a player “wasted” 2 hours in a nightfall underpowered, likely, they knowingly accepted the difficulty and were determined to complete it. To come to any other conclusion strips the player of their agency in the matter. Despite what much of the Destiny community would have you believe, there are a lot of gamers who love a good challenge.
