I think quests need a couple new things. For instance, it would be awesome if there is a text explaining what you do to actually complete the quest (when you've pressed the 'do quest' ), instead of just the title. This would make quests so many times more fun to do!
In addition, ever thought of adding images to the quests? Take, wouldnt it be awesome with a well made image picturing a <Insert character class here> battling in, say, the new 1700 level quest, "Protect the People of Lanarea from a Viking Attack"? Me, i'd enjoy doing quests with this kind of feature much more!!
Also... Quest exp awarded really should be fixed!! Its way too low compared to battling monsters! I think it is a bad thing that doing quests for a certain drop feels like you're standing still in your leveling!
