Anyone super excited to link their Destiny 2 account with their Blizzard account well ahead of the game's launch date is free to do so as of today. To do so, all you're going to have to do is visit your Bungie profile and link it with your Blizzard account, which isn't that hard of a process. Ultimately, all doing this now will save you a handful of minutes when you're forced to do so anyway at launch or when the beta releases...so get on your Bungie profile and do it if you haven't yet.
