It allows you to temporarily upgrade your account in a party
Blizzard has now made it a lot easier to playStarCraft IIwith your friends, regardless of what version you have. All you need to do is party in-game with a friend who owns a “better” version of the game. So basically, say you own the Starter Edition — if you party up with someone who hasHeart of the Swarm, you may access pretty much everything, as your account will be “raised” toHeart of the Swarmtemporarily.
Ranked and unranked matches are for grabs, as is the entire Arcade. The only things off limits are clans, single player, and the ability to play as anyone other than the Terran (which is irrelevant in the Arcade). This is a nice move by Blizzard, and feels like something the “Blizzard of old” would have done. In fact, the video even mentions that historically they alreadyhavedone something similar forWarcraft IIandStarCraft(they did it forDiabloas well, where you could only play as a Warrior).
