Craglorn is far too populated nowadays, when all crafters 40+ are forced to do writs in Belkarth. With 1T there is no any reasons to have turn ins split according to old zone levels.
I think it would be great if we could accept writs in any city and turn in at the same city all writs does not matter what level they are. It will help both to decrease lag in overpopulated Crag, add some population to currently quiet cities plus it is convenient when you level crafts, you don't have to jump into 3 different places only because you alchemy is behind you smithing.
