Assignments getting too difficult

I am a L99 Player so have pretty much everything you can get. However this assignment, which I did, was pretty rough. 18xTapestry 3 hours+(72 cloth, 36 Paint, 36 Glue(same shop) that's 144 Chemicals)). A very large proportion of my tasks are now based around the "New" shops and all are 2-3 hours final item with ridiculous input costs to make them. For those interested it took about 36 hours to do with no speed ups used. But I do play with two cities, the other L85.
