From todays patch notes TRADESKILLSTradeskill work order and rush order writs are now available in guildhalls for tradeskillers above level 110. I just tried to obtain a rush order writ for my 120 Sage on Antonia Bayle and was told the same story of not now. This was in my Guild Hall. I am not sure about availability in town.
If it made the notes it should have made the cut. Unbelievable that such a basic function still isn't working this long after release.
It looks like only part of the files for the writs made the update. I will get the remaining files to live as soon as we can. Sorry for getting hopes up!
