so like the above says, i have just unlocked the hearthsteed mount to use on WOW, by winning 3 games on Hearthstone. i know by playing overwatch you can unlock winston as a battlepet. But, i wondered if anyone had a link for all these types of unlocks please ?? or, is there even any more like this, where you play another game to unlock something in a different blizzard game ? thankyou
