They're doing away with Light Levels being tied to gear. I'm finally going to scrap my 2nd hunter and start my warlock. I have a bunch of exotics for it already in my vault
But what’s not all that’s been changed! The way Bungie is approaching leveling up is now tied directly to experience. There is no more Light values on armor, so that “experience now feeds directly into your level progression all the way from 1 to the new level cap of 40.”
