So I'm assuming we are going to have to give up our unique Blizzard gamer-tags once Steam is up / Blizzard down.. which would be a bummer, I would hate to have to be 'doc13591' on Destiny 2 once Steam goes online. Maybe there are more con's to pro's when having a bunch of people with redundant names that are only unique by hidden numeric values(in game). Either way, kind of a bummer.
Won't it just change to your steam name (which is changeable at any time) like all the rest of the steam games do? Interesting thought, i hadn't really thought about it myself until now
