On the other hand i dont want to click on every NPC to discover who has a quest, its even worse when there are only very few quests available. Maps are OK as long as they dont show you every detail regarding quests/mobs/dungeons etc...
But you don't have to click every NPC to discover a quest if questing was done differently.
In EQ you didn't care to go to the quest giver to talk to them you just killed NPCs and when they drop a quest item; you keep that. Make the quest item leads you to the NPC (for instance a letter belongs to the husband of NPC X in City Y) you looted the letter you go back to town to find the NPC if you want. THAT NPC doesn't need to have an exclamation/quest mark.
But then again I'm not a fan of quests like that. I don't mind quests like Crushbone Belts; which are repeatable "errands" actually more than quests which are there for you IF you want to but not really necessary (but don't make quests rewards us with XP please). Why do I fear quests and that exlamation mark? It's because these things are another way to restrict our freedom another form of hand holding that I despise. I'm sick of being told what to do. Instead, I want to explore and if I kill that Orc and find something then that "quest item" must give me a lead to something and I don't have to go to place X to switch a quest on, then go to place Y to kill/collect then back to place X. That system is retarded.
Few epic quests are great but I don't want GPS maps leading you exactly where you have to go and I don't want, again, exclamation marks. How do you find the quest NPC? first, you don't have to because questing is NOT the game (I will cry with joy if Brad manages to make this true). Questing should be something you want to do; not something you should do. You shouldn't be penalized for not picking up a quest (hence why I don't want them to reward XP) and if itemization was done right and level curves long enough then you shouldn't be missing out much anyway.
I think a game, to me, is far more interesting if I just decide to step out of town with friends to seek fortune and glory entering the Crypt of Doom. There, in the crypt, we will find our rewards whether by killing the bosses (to loot the items; itemization should be the game.. don't let trash mobs drop loot. Make loot rare and make loot lasts you a few weeks instead of a few hours in today's games). We can find a quest-item dropped by a named monster and if I am interested I can read more about the item. Whether the item states something (like right clicking on it it would tell you that this item seems to belong to a blacksmith of town X) or maybe make some classes able to "identify" quest items to give you more details (which increases player interdependency).
More dungeons, more content and more challenges. Less quests/errands/chores/hand-holding.... please.
