6 - An open fate group system on boss fates. Pretty much how it would work is you can have a setting to either accept or deny this (so it won't screw with your dungeon Q times, or even make this a different kind of party so it doesn't do that) and when you get to a boss fate, let's say svara for example. There would be a "join open group" or "create open group" open, and that would build up parties for fates quick and easy.

7 - Vote to kick feature in dungeon finder. I'm sure by now we've all ran into that annoying party member, that just won't do anything, or they're just a prick.

That's all I can think of for now.
