Set items.
No, they shouldn't be implemented as they were in Diablo. I could never collect all set, and even if I could finally get all those pieces together, stats for that equipment completely sucked as I was to that time much higher in lvl to even use it.
It should be done as it is in DD with dragon set. Sure, it may be done through smaller side quests. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
