Long story short, I came to this conclusion after playing Heroic Menagerie. So here is the idea- Scale ALL content in Destiny 2 up beyond the current expected power-levels. Not excessively so but enough to make the game actually challenging the entire way through as you climb. This way players feel engaged with the content and challenged rather than grinding through monotonous boring/easy content. Focus again on Prestige-Content by simply making them be activities that scale PAST the current level cap. Add superior/unique rewards to Prestige content (like Nightfall exclusives and hard-mde gear like in Destiny 1). Do this and you can even bring back Prestige Raids. You don't necessarily need to add new mechanics, don't need to remove revive tokens- just the same content but scaled upwards so it's still challenging for level-cap players. When I say Prestige Raids that scale past current cap- I mean perpetually, as an example- Last Wish is currently still at it's original intended power- but Prestige Last Wish would be set above 750 even though it's an old raid. This way it's again ALWAYS challenging, and you can push players to do this version of the content by keeping the Prestige gear updated and superior to standard gear via additional perks or mod-slots etc. Bungie wants to make this game more of an MMO, they want to reward their 'core' player base? This is how to do it.
