I made it to 370 Armorsmithing fairly easy, I didn't do it overnight though and I did spend quite a bit in auction because I was too impatient to farm minerals but it wasn't too bad. I haven't gotten too far into the other trades yet but I am having a lot more trouble with enchanting then I did with Blacksmithing. The only reason I haven't gotten to 375 yet is because I don't have the other felsteel plans yet, only the gloves, but now that I have my flying mount that shouldn't be a problem.
