Dunno what Blizzard’s stated reason because exchange rate change doesn’t make too much sense. But it means Canadian players who farm gold to buy game time will now have to farm x% more to buy the same amount of game time they could yesterday.
My guess is it’s a test case with a small sample to see if this change will squeeze out more time played.
Or less likely, maybe too many Canadian players have maxed out their bnet bucks and Blizzard wants to drain their accounts. lol
