D4 in-game Armory and stats/achievements confront

The game has been out for 1 year now, and I’m definitely a huge fan. However, I don’t understand why some interesting functions that were present in D3 have not yet been implemented; among those I would like most, I’ll say an Armory that allows you to consult every single aspect of the character/account (even from the website, as well as in-game), in particular the statistics (mobs killed, elité killed, gold looted, best leaderboards time, etc), and which also allows you to compare the statistics and the achievements between players (friends from friendslist or clanmates or wthatever). What do you think about it? I think it would be a great feature! I think you all remember the D3 armory, in any case I’ll give you an example link from a user I found on the forum: https://us.diablo3.blizzard.com/en-us/profile/MerLock-1557/ career.

And this is why they get no more money from me…features in D3 that were absent in D4.
