I'm sure anyone who frequents runs like I do, be it missions, JK, Shadow Lair, or otherwise, knows where I'm going with this - You join a party, and it just so happens that the only person who AFKs in the middle of the stage is the party leader. You don't want to go back to Haven and waste your spent CE, but you can't kick them either (or insult them at risk of being kicked yourself).
"So don't join parties randomly", you might say - not everyone has the time to build up a friend list though! Some people may only have 30 minutes a day to play, and that time matters to them. How many times have YOU sent out invites to your Friend List and had only 1-2 people reply at all?
Going solo doesn't work now that it Restricts the party, so that's not an option either. Plus, even if it still was, reinviting people gets tedious/annoying, right?
So, I think it would be a great idea for there to be an option to change who has Party Leader status. At least then if someone has to go away unexpectedly, the current leader can inform them (or at least switch over who has control if he has to go for longer than expected). Alternatively, you could allow a party member to request a "Party Leader Change", and the existing members vote on it under a time window; if the majority (3 people in case of 4, 2 in case of 3, etc) vote Yes, then the leadership is automatically assigned to a random new member.
