Concepts from other MMOs that would be utterly anathema to FFXIV

[Avidria]

Being forced to play alts in order to experience another job class. I do not miss what from WoW, having to mail material to myself because of my different professions. It was so tedious having those limitations.

Funnily I feel exactly the opposite about this haha
I've been an altoholic in every MMO I've played until this one, and being stuck on one character has been a consistent source of frustration while I've been here. Being able to do any role on one character is nice, but it means I'm stuck with... one character. I can't just swap to an alt to get a different look, feel, and personality for my characters because in my experience playing alts in FF is an actively miserable experience, and I keep buying Fantasia's purely because I want a new look and can't just. Have two (or three, or fifteen...) characters to get what I want without feeling like I'm losing time on my main because absolutely nothing is shared between them

On that note I guess my addition to the thread would be alt friendly features mail and trade between alts is something I'm also used to from pretty much every other MMO I've played, and the shared bank in Aion (and I believe swtor had this too?) came in handy quite a few times. Add in shared mounts and minions and I'd be a lot happier...
