1) Linkshell embles/shield crests
Only if they make them customizable. They are quite ugly.
While I agree, many don't think so, and they do contribute to the roleplay factor regardless.
2) Retainers/bazaar mules
It's good, but I'd never use it.
Well this is more than just convenience. There are many people who have second accounts just to mule/bazaar efficiently. Although getting rid of that may not necessarily be in SE's best interest, it is still a very practical feature.
3) Better crafting system
No, not in the slightest. Crafting should not be a mini game.
Why not? I dislike the random win/lose thing. Regardless, I wasn't asking for a minigame, just something to make it more appealing. As I said, I don't want them to just copy the game style.
4) More teleport points
But you have limited uses.
Still allows for easier access. And again, it doesn't necessarily have to be the same.
5) Show status effects of party members
As a WHM, I like this idea, but it'd put too much on the screen in large PTs.
Agreed, however it could be reduced to only important status effects or restricted to one party.
6) Show remaining time on own effects
I think this is unessisary, too many variables.
Not sure how those are related, it should be easy enough to determine.
7) Multiple linkshells equipped
Wasn't a fan of that feature.
I wouldn't use it either, but it opens possibilities to people who could use it.
8) Better chatlog filtering/organizing, customizable tabs, different log windows

9) Minimap on the screen
SE already stated that this was unimplementable in FFXI.
Oh? Must have missed that. Still, it is a feature XIV has that would improve XI.
10) Customizable HUD
{Please use the auto translate function.}
Being able to adjust the position of screen elements, chatlog, HP bar, Party list, etc.
11) Using the numpad to input numbers
You can already.
Not the last time I checked, although admittedly that may have been some time ago. Did they change that?
12) Built-in IME support

13) No POL, better/faster login and updates

14) Specific market wards

15) Designated bazaar area

16) Searchable bazaars

Anyway, this is not an official list or anything, just some things I noticed about XIV that seemed more advanced than XI's facilities. Some of them are basic to implement (Numpad), others more complex (IME), some are minor features (Linkshell emblems), others are huge (Retainers). Either way, this game still has lots of things it could use from XIV, just as the other way around.
