They didn't say you have to stop using it. But one day, imagine this. It's year six. You're still using your fatebringer, because you adamantly do NOT want to experience new things while complaining about lack of new things in this game. Each dlc adds nothing for you. You complain about it, while you still use your 365 fatebringer. "There's no new gameplay!" You say as you refuse to change up your style to get with the times. People won't raid with you. You haven't beaten anything but Oryx normal because you refuse to use anything but fatebringer. "But this weapon has better atk, stats, and perks for this!" Your fire team says. "NO!" You scream, "I WONT LET BUNGIE CHANGE THIS GAME WHY WONT BUNGIE ADD NEW CONTENT"
