Not unless you’re willing to pay them more money to bring that contents gear up. Seriously though, it’s a bad reality but I’m pretty sure those activities will become pointless and the gear as well outside of casual pvp. The only use they’ll provide are pretty sceneries and any lore that may have not been acquired from the player. That statement of the pretty sceneries only applies to three of the four since the moon isn’t really pretty to look at imho.
At this point I just wish Bungie would just remaster D1, give it ledge grab, fast travel, the D2 subclasses but with D1 ability trees... 60fps and 4k. I would Preorder ASAP!
I really would too and they could actually tie the darkness subclasses a bit better using the dreadnaught, Titan, and Europa. Just so much better things they could do if they just said destiny 2 never happened and was a fever dream.
