What would you like to see in a quest? If you had the reins, what would you do with it?
Personally, i would like to see quests that offer a choice that could effect the layout of future updates. Say a raid that has two factions fighting and before the final fight you could choose a side, each of which would offer different loot options but depending on which option got the most completions in a given time frame, would have an effect on the next mod.
Example, you can help the troll overlord overthrow the demon patriarch or vice versa. if the trolls win, then in the future, they maybe allies, but if not then they decide to attack stormreach. Maybe the demons give you uber items, or decide to put off killing you for a while. or lie and smite you anyways. It would just be cool to have some direction in the storyline and would be good to get players involved. Would you go for the uber loot if you know that the reprocussions could be disasterous??
And i would like to see the return of some old faces as well. Maybe that guy in the beginner quest (drexelhand the devourer???) didn't die, maybe he was on the verge of death and made a deal with a devil. he now serves as a host for this demon who is bent on enslaving the kobold race!!!
Just some idea of mine, now lets here some of yours.
