I guess this is a lot on this subject, but just put it back.
It would be nice that we could kill haven, either that or put some haven where you get exposed to that can kill you.
They could also put the option to enable or disable pvp mode so if you can not kill you off.
Another way would be to reach a certain level you are unprotected and can kill you anywhere.
This would cause people to join the guilds and cojieran walk by force to protect and face each other
I want to see looting enabled on top of this, too. Take the EVE online approach and implement a guard system but have them move slowly enough that they can be evaded.
