Another thing is the loot feature. If you die anyone who you had given permision to loot you can get all your stuff. This is usefull if you plan on starting another character. For example, you have a level 85 zon with gaze, shaft, WF, etc. If you died, you would be pissed that you lost your stuff more than you would be pissed that you lost the zon. So if you had given someone permision to loot you, they could get your stuff for you. Downside is you have to know who your real friends are.
