If daily quests are released with the Thieve's Guild DLC, I hope they aren't the same kind of repetitive ones that we got with Orsinium and Cyrodiil. It is likely that they will involve stealing an item or maybe multiple items of value from somewhere in the world. I know it may be difficult, but it would be nice if there was some randomness to them. Such that it is not the same few items and locations every time.
The same should go for the Dark Brotherhood when it is released. Being ordered to kill the same 7 or 8 npcs over and over again will get old really fast. What does everyone else think?
