it would be a simple fix and it is pretty important. People shouldn't have to create whole new Linkshells as a work around.
Was also nice in XI how looking at your LS list would show you the job/level/location of everyone online. It's a lot of simple things missing like this that make me scratch my head. They obviously know how to do it since their previous game has it.
I think this about oh-so-many things; hopefully they'll figure it out soon, they do have lots of people from FFXI working on FFXIV now, right? Of course, I guess you could have said that about Tanaka, too... hmm... >_>
