First off, this complaint is about how things that don't pose a problem on their own, are a problem together.
1) Because of the way that the quest system is setup, you don't want to have more than 1 quest running at a time.
2) Because of another problem, that of non repeatable quests you changed it so that we can't discard a quest anymore.
3) Some quests require that you complete a second or third quest in order to finish the first.
4) Since some quests are linked, if you don't find out about the second quest to finish the first, you are stuck with a quest that you cannot complete.
Now maybe I missed a clue somewhere, but in the case of Hiacheius's lost golden shield diagram, I was told that I had to go and see Canyt Klannarr and get a quest from her in order to finish the first. Now if another player hadn't told me that I don't know if I would have ever managed to finish the quest. Like I said there may have been a clue that I missed, but in all that I did I never saw anything to point me in that direction. And since its known that having more than one quest open at a time can cause problems I wouldn't have gone around asking for quests in the hopes that I would find a solution to the quest I was working on.
Now, I propose the following solution.
1) In the case of linked quests, change them from being two or more separate quests to just one continuous quest. This way the person would still have to find each of the npc's and perform the needed tasks for the quest, but they wouldn't be constantly thinking, do I need to break the 1 quest rule and take on a new quest to finish the old quest. And in the idea of linked quests I am referring primarily to quests that give you a reward thats used to finish the previous quest. In the cases where one quest unlocks another quest this wouldn't be a problem cause you would only have one quest open at a time.
2) Allow the discarding of repeatable quests.
3) Keep a lock on non repeatable quests so that you can't delete them.
Thats my rant for the day.
