suggestions on craffting

hello i was gonna suggest that when u are crafting sucks that u have to go and get the items u need from your retainer well would it be better for everyone to if u have the item in your retainer and lets say u wanna craft and u dont have the items in ur item bag instead of going to retainer and getting all the items u need the only thing u do its change classes to craft and if u have the mats to craft that item u want u can craft it with out going to retainer and getting the items waste of time
