I'm playing my second character, in Immersive solely again. I have only finished the quests up through the Cromwell chain and one side quest chain in addition. My character is level 23 and rank 10 Sharpshooter, no levels in any other class. I think the Xp gain is way too high even for immersive mode. I'm having fun but even with hard settings there's not a lot of challenge and progression feels stagnant.
