Social Aspect is driven by players.
There are more social tools than before, but players need to use them.
Cut out the tired "casual" argument. There is plenty of content for the "hardcore", you just forget that there are players who are not you.
If people can afk, then thats a social problem where everyone else simply ignores or tolerates it. See above.
Empty servers are again driven by the community.
See above, again.
Dailies where there are no longer the mandatory items such as shoulder enchants. Craftings can be provided by anyone else, without the need to earn them yourself.
Aside from earning lesser charms, which is a valid complaint (which nobody ever brings up) dailies are largely fine as they are.
Valor has other likely more efficient sources.
Alt Unfriendly, when you complain about the reputations which offer a huge bonus to any alts reputation grind which is actually optional at best.
Mounts being account-wide, many account-wide achievements. You just call it alt-unfriendly without any supporting argument.
Because you cant give one.
The Lore is a personal opinion, I like it. You do not.
Get over yourself.
Segregation by tiers is done by players, by the community.
Notice a pattern here, how a considerable number of your complaints are driven by player decisions.
A player community, which you are a part of.
Instead of whining, take a look at the real problem.
Those around you, and I would not be surprised if you were also part of it.
You pick fault with "casual" content, but then complain about segregation of players by tier when you are doing exactly that.
