They do make some Raid weapons attainable for solo players. Have you done Rivens wishes this season? You can get 5 red borders on a weapon and craft it or pick up the set roll on 5 different weapons each time you complete the quest. It’s easy to obtain them and all 5 can be done in a hour or so. Theres 2 Brave weapons from Raids too. Forbearance and Succession. You can also purchase a handful of raid exotics from the kiosk at the tower. You can get the spoils by running solo chests every week on all 3 characters Hope this helps.
