Hearthstone with Friends has been a slightly complicated process since launch - more often than not involving an external meet-up via Skype, followed by an exchanging of numerical game IDs from a main menu determined not to minimise under any circumstances.
That’s to change - and in WoW, and Diablo, and StarCraft - with the introduction of direct chat to the battle.net desktop app.
Look for the Friends icon in the top-right corner of battle.net on next login. Through that, you’ll be able to access a contacts list, replete with statuses (Online, Busy or Away) and individual chat boxes.
Desktop messages will show up in whichever Blizzard game you might be playing at the time - making a round of Hearthstone a valid way to fill the gap before raid time, for instance.
You can customise which activities trigger pop-up notifications according to your taste and patience, and unwanted friend requests can be reported and/or blocked with a press of an ‘!’ icon. Regular compadres can be tracked in a select sub-list of favourited users.
Chat doesn’t quite work both ways: if a character friend within WoW or Diablo III messages you in-game, no notification will appear on the desktop app. But for now, this is a useful way to further unify a set of games which otherwise share plenty of crossover, in lore and audience.
Let's not get carried away though, eh Blizz: Hearthstone should never, ever get text chat for games with strangers.
Do you think you’ll make use of battle.net chat?
