They keep saying they would like to address the reason for having a full quest log in the first place, but in the mean time, why not let people accumulate as many quests as they want? What does it matter if someone has a lot of quests in their log? I can see putting a limit of like 100 so people don't have absurd amounts of quests, but I don't see the big deal of letting people hold on to a lot of quests if they want.
