on offi they did remove this feature in the past around c4 or c5, but it was only because they were aiming for a more casual playerbase in order to increase subscriptions. also, with the introduction of A~S grade gear, the risk of loosing items after months of farming was becoming a real threat for the game itself, since those items were only craftable and couldn't be bought via NPC, unlike low-tier C~B grade gear from the Luxury shop. all in all, it would probably reduce the amount of griefers and make the gameplay a bit more "relaxed" for everyone, but it would also reduce the level of awareness for griefers/PK when someone goes out of town to exp. people would probably still group up together in any case, since at higher levels it's impossible to solo mobs with crap equipment, but in the end it's up to the admins to decide.
