Through November 5, 2021 players on Battlenet can change the battletag associated with their Overwatch account for free. It's only available for the limited time through the 5th of November, and you can only grab it if you don't already have a free name change on your account.
So if you already have one, use it and snag another free one, I guess.
It's a great opportunity if you, like Blizzard, regret the name you chose. Such as, for example, a prominent character in your shooter.
For you, however, it's probably more like when I chose my StarCraft username back in the 90s and misspelled it.
As we introduce a new name, you might have the desire to do the same. We are providing a free BattleTag name change to all players.✨ https://t.co/gYMbJd7w61 pic.twitter.com/C8gGTmCBNDOctober 22, 2021
