I like the idea of besieged, but with how busy Uld'ah is and empty everything else is... What might need to be done to lead to a good set up is make Hamlets more accessible (closer to the roads, have more important STUFF, don't care what but make it so we want to be split between there and towns. Maybe even balance the server load a bit!) and then have it so Hamlets come under siege.

We kind of see this already with Garlean 'assaults', even if it is just a bunch of NPCs spawning and then hanging out around some Oilbugs or Coblyns until we come to kill them.

I wasn't around much long after the third FFXI expansion so I must have missed out on Nyzul, but it seems similar to the principle behind Disgaea's item dungeons and that old PS1 Monster Tower game. I absolutely LOVED the idea of endless dungeons, bosses and puzzles. I'd be down for this.

Love all the responses this thread is seeing now too.
