Doing the quest to gather all items is already hard and long enough so why the hell do you make all npc who give us the quests vanish?
I haven't seen Alvin once during the last 3 months and there are always people camping them.
I'm not playing AO to wait 10 hours in line for my turn just to give an item to a npc.
I work during the week and can only play the evening and waiting for a npc doing nothing for several hours isn't my vision of fun. Just for this reason I will leave the game for another which doesn't have this lame feature asap if you don't change it.
I can understand named mobs with special loot having a longer respawn time than regular mobs but in Alvin's case it's a quest godammit and the time spent hunting robots should make up for a respawn.
Even EQ, known as the king of campers doesn't do that with quest npc.
I love doing quests because it changes from the daily missions but this current feature kills all the fun.
Please change it.
I'll keep bumping until you do it or until I'm gone to another game without such a boring feature is released.
