I'm an Xbox guy but I do have a few tips to help you get higher light. 1: use bnet to find a clan that suites you. I'm in a group for parents. Finding the right clan makes this game infinitely better. 2: use the bnet recruitment forum to find raid or NF groups when you can't get people from your clan. The other LFG sites/apps are kinda dead right now. 3: if you have multiple characters use infusion across all available characters to make one of them as high light as possible. Then run your Nightfall, Zavala bounties, shaxx bounty, Raid, and archons forge. Equip any higher light armor you get as you get it and infuse any higher light weapons you get into your favorites as you get them too. Once you've completed all those things for that character for the week transfer all new highest light gear you have to your next character. Equip the guns ghost and artifact. Infuse all the armor into this character and repeat all those activities. Don't worry about losing a cool exotic armor piece to infusion. You can always go buy another one from the kiosk in the tower later. If you do all that across all three characters before reset you'll have a character at 400 or damn close to it. Good luck guardian!
