Agreed. While my own personal LS is extremely small, I am part of a large LS as well.
And the constant restructuring of LS's for no reason is quite frustrating - and I'm not even the leader having to do it.
There are many reasons LS Leaders should be able to do as they wish with all their LS functions, whenever they need to.
An unruly or disruptive member, an inactive member bloating the member count, or they just don't like someone. It's their LS, they should maintain the priviliges.

I'd be willing to wager most wouldn't even mind an NPC or LS-Management board they could visit in each of the adventurer's guilds. There's a lot of ways to impliment it, and it could be really simple in terms of capability.
And as others have said... Just allow LS leaders to boot dead weight, and this becomes much much less of an issue.

Then you get to the juicy stuff that can wait, such as LS member tracking on maps, LS member events and instances, LS priviliges (such as a sub-command that allows leaders to speak only to sackholders), signing crafted items as being from a specific shell, etc.

But I know the team is working hard and doing their utmost to see this game thrive.
Let's just hope this particular issue gets dealt with a little quicker than seems to be planned.
