I think using DR as a shortcut buy jumping of a cliff, attacking ulbers barehandedly or just typing /die is a bit spoiling the game and really makes no sense from a RP point of view.
Therefore I think it would make sense to have several exits from DR which vary in their behaviour:
-put you to a random place in yliakum
-put you to your races hometown/spawnpoint
-teleport you somewhere within the DR
This would a) stop the DR shortcut abuse and b) make DR more interesting because you really might wander around a while before you get out, because you don't know when which exits leads to wich place.
The option to travel to DR by magical means without needing to die sounds good and would allow cool quests like 'find lost soul in DR and guide to get out' or something
Teleportation as a general travelmethod... yes sound good... but it should be really difficult even for advanced players (rituals needing rare ingredients, high level spells). To allow fast travel also for lower level players, there could be NPCs offering magical travel (for ridiculous amounts of money of course

)

I think if teleportation would become commenplace, PS would suffer from shrinking in the players perception. Therefore the normal travelmethod should stay walking...
Just my 2 trias
