Check out Kalifas Artexas crafting ideas, he mentioned in one of his posts about a couple of crafting games that would be fun, one of them was based off of Guy's grocery games, if you haven't seen that show you definitely should to see what he's talking about. Doesn't necessarily have to be with just cooking. Anyways my fiance and I have been grinding all the crafts to 50 and the most tedious thing I've noticed is farming farming farming crystals(shards) like 3 days in a row for me at a time. Also as you get higher you have to go out and farm this and farm that etc.... But with the GP it goes down real quick and takes forever to fill back up. When I need to use actions to help with crafting and then i'm waiting very slowly for it to regain again that is tedious in itself.
