On our btags, not everyone wants to get the message "Hey lets run mythics" right when they login or "Hey can you tank this" all the time, or deal with that friend who plays Overwatch and keeps trying to get you to play heroes of the storm with them for skins because there's an event and they don't know how to play and is getting mad.Personally I like to just get away from everything and do my own thing once in a while, much like a plethora of people do in real life. Spend some me time, do what I want to do without being bothered, guilt tripped, or whined at over helping so and so.Actually, you shouldn't NEED a reason as to why you want to appear offline to your friends. Maybe you just wanna solo stuff without being interrupted.Inb4 "well why did you add them then!"That's irrelevant, message services like Skype and Yahoo messenger have options to show as "offline" so asking for it to be implemented for WoW isn't uncommon."In the coming months, we're planning an update to Battle.net that will give you more control over your online presence when playing Blizzard games. Soon, World of Warcraft, StarCraft II, and Diablo III players will be able to select "Appear Offline" as one of their Battle.net social-status options (along with Available, Busy, and Away) for those times when they want to wander Azeroth by their lonesome, dominate the galaxy in radio silence, or slay demons in solitude. When you choose this option as your status, all of your Real ID friends, BattleTag friends, and character-level friends will see you as “Offline” in their friends list whenever you’re logged into a game.The “Appear Offline” status option will be added to World of Warcraft, StarCraft II, and Diablo III separately in future updates for each game. For Diablo III, we expect to add the feature in a patch after 1.0.5. For World of Warcraft and StarCraft II, we expect to add the option sometime after the release of each game’s upcoming expansion.Thanks for your continued feedback, and we’ll share more information on the availability of this new feature in the months ahead."Just an FYI patch 1.0.5 was released five years ago....Thankfully there was renewed interest in offline mode with the introduction of Overwatch, so maybe they'll have it some day...tl;dr Blizzard said there would be an offline mode 5 years ago, still no offline mode.
