Not sure why people would downvote this. Its a legitimate question. The salt on these forums is massive. That aside. Finish the Forsaken campaign, unlock Dreaming City and get to level 50. After that (if you have the season pass) you can start the opulence invitation quest. This will reward you with a full 690 power set. At that light I would suggest checking out Black Armory first. The quests to unlock the forges are tedious but the guns are very good (pulse/machine gun/hand cannon/auto rifle to name a few). Also some very good exotics in there too (Jotunn especially). After youre done with that you can totally skip Season of the Drifter if youre not into gambit. There is a ton of grinding involved there with little reward. Save any cores that you get, do the gunsmith bounties and buy from spider when you can afford. You are probably lacking cores so do not infuse anything until you reach max light (750 now). You can do the season of Opulence stuff at 700 light, the menagerie is very forgiving and a rewarding grind. Eyes up guardian and welcome back!
