Been on the game for 7+ yrs and got cooking lv94-99 (others crafts over 20+) on 2 jobs and, one of them took me 2 years to level up back in day. Only crafted when felt like it .
Crafting is always solo time if not sorry, and it like that on many other mmo's that I played ,and buddies and gals I talk to played say the same thing, there is no reason to try to reinvent the wheel. Time to relaxed do something different , not spend month shouting in jueno for help on something.
Takes 2 minutes just to start the synergy item and then got delays and all that stuff. trying to repair it and ect... yes i know I should use 2+ players, but crafting from all my exp. in gaming is something to do to kill time while waiting for party, chatting with friends, relaxing, not something to go and throw the keyboard or controller as far as you can while spaming your feed fewell into it.
I Know i might be missing something on how to use the furnace in automatic mode , but why cant you just put in the ingredents and game does the rest for you. It takes out fewells automatic and rest of it does on its own per your skill level automatic.
Get rid of the parts were you need more then 1 person,, unless its a super rare reason.
PEACE
