Basically add a tick box at the character select screen, which relates to each character before you play them.
You tick a box to say "Play in hard mode" and it will automatically select hard mode on the party bar. You can obviously still choose normal mode using the same buttons, but this will mean you are automatically set to hard mode everytime you enter outposts or instances etc etc.
Its a bit annoying when you leave a mission or quest or dungeon or change districts and it re-sets you back to normal mode and you then start a new quest or dungeon in the wrong setting.
