Dying in Marni's realm is very annoying. 
You have a 5 minute re-entry cooldown while your buffs keep ticking down.

Either don't kick players out of Marni's realm on death, or let them re-enter w/o a 5 minute cooldown.

Why should a death in Marni's realm be more inconvenient than a regular death? You are already subject to crystal loss. 

If there was a special mob/boss spawn you can't kill it anymore.

You can't re-enter for 5 minutes so you have to swap to keep your buffs up.

Upon exiting the marni's realm you end up in the middle of someone's rotation. 

The whole instance of grinding is pretty much reset and it's very annoying.
Just let people use elion tears or fairty skill to ressurect within the realm. If they choose to ressurect at town/safe zone, then you can boot them out of Marni's Realm.
