Nope, game is an online only multiplayer, main content is always fireteam required whether through matchmaking or finding your own team. If you are not likeable enough for others to play with you, or, to stupid/lazy/arrogant/ignorant to find a team then that’s your fault for not playing the game how it’s meant to be played. Good luck in a raid solo unless your better than redeem etc, good luck in trials 1 v 3. Said enough, peasants will always be peasants.
