+1 for all the topics that have been mentioned on this thread so far (with the exception of the changing jobs while in combat....)

The only thing I'd like to see added to this list that I'm kind of surprised that nobody has added yet is the ability to promote someone to be the LS holder/leader. With the state the game is currently in, I'm sure that more than one LS leader has left the game or gone "inactive" for a long period of time and it is hard to manage a LS when you are not around. Our LS had this problem in FFXI as well when our leader stopped playing the game. We went over 3 years with him not playing. Thankfully, he kept his account active for that entire time so we wouldn't have to recreate the LS that was around since NA release.

Anyhow, give the ability to do more with promotions, get rid of the restrictions to LS size, give info about the people in your LS (class, rank/level, location, online status as well as "last online" info, sortable list that you can sort by whatever you want), /lsmes, more options for colors/shields including player created options.... simply more. I'm surprised that all this was not included in the first place or has yet to be implemented with how SE focuses on "group" play, then limits how to interact with your "group".
