I don't remember if it was back during Blizzcon '09 or some random blue post, but didn't blizzard say that they planned on making it so that achievements are account-wide(B.net)?
What ever happened with that? I haven't see any scrapping or continuing information on that.
I would have loved it! I know myself and a lot of other people would switch their mains so much easier if they didn't have server-first or hard to get achievements tied to that one character.
I'd love to have an ironbound or icebound mount on my alts. Or "Light of dawn", 'Grand Crusader" on my other characters. I mean I am still the one who put in effort for those achievements.
TL;DR
What ever happened to the idea, and would you approve?
