The way the current chest at the end of SWV works promotes (in my opinion) ninja'ing. The chest can have multiple people inside it at all times. There is no ingame system roll for the items. The GM's don't interfere with loot disputes. This is even worse off than raiding, since most groups will use the party finder. This isn't a raid where you choose to let someone be the loot master to hand out the loot, or use the roll window. YOU put your trust in the group. YOU make that choice. There is no choice with the SWV chest, it just exists.
So, if I see the item I want, instead of rolling for it, I'm better off just taking it, cause there is no punishment.
