One thing I’d recommend is just do the capstone and go to T3… the power jump after getting the gear that isn’t soft capped is insane… I was struggling T2 with a level 52ish Barb and I hit the bullet and grinded the story to get to T3 and I was shocked at the change… still gotta watch the survivability… but damage took off.
Welcome to the club! I’d love to hear which one is your favorite (cough IX cough) in a few years once you’ve played more!
