Paradox?

so if every one has there own story line how is it possible to be a multiplayer game? is it gonna be like presearing for each section or like a run to droks and skipping all of the storyline? and if I get a rare drop from a one time event how much will it be worth or will that event ever happen again? and if it does will I have to re do it or will some one else and write over my story?

nah the events reset every few months(or even weeks depending on the even) and there will be different quests for everyone based on the answers to your questions in the character creation
