If your looking to be a tailor just whisper me because i keep all the supplies since i first started, only takes about 3 hours to reach 375 so don't sweat it, in account to it's quick and easy 375, the MATS you need to make high end PvP gear..which you will need 2 of each cloth X60 which each one takes 4 day cooldown.
Btw if anyone could help me with Engineering that would be cool.
