Please I would love to know where the level ups are? I only have "quest steps" now and it's awfully complicated trying to google where and how to complete them.

Bounties from vendors give you powerful gear dreaming city is a good place to go to too. Gotta get through the content from foresaken before jumping into armory. I only get to play a few times a week but I’m about 620 and on my titan with my hunter and warlock around 580. I play casual I haven’t done much in the dreaming city or raided primarily just Gambit and the occasional crucible. Once I started picking up bounties and getting lucky with prime engram drops along the way I went up about 10 or so points easily in a night. This is coming from someone who still hasn’t done the first forge and puts in maybe <10 hours a week. Bungie put it a lot of stuff for people to figure out on their own because that’s part of the excitement of discovering something in game. If you’re struggling with not knowing how to finish a quest maybe look someone up on YouTube and you can learn what to look for. The game won’t play itself for you.
