This could be interesting. Instead of saying i cant to to place A because i don't have the necessary lvl. It could be based more on i've been to place B and have this new armor, crystal, guide ets. and i can enter this area.
I think this is just gonna be really item based. People always said the wanted to have more interactive armor and weapons etc. I think this is where they are leading to.
Edit: more interactive weapons and armor in FFXI that is
