I don't know about you, but I really hate delegating jobs to new immigrants. It's not so bad at the beginning, but once you have to reassign over 20 jobs a year...well...it's a pain.
What makes it more of a pain is the sheer amount of professions available. I feel a fair amount of them are useless. It's annoying to get a Fish Dissector, only to need a Fish CLEANER, and now you're forced to train him in an entirely different profession, despite the two being very similar.
I propose we consolidate some of the more useless or similar jobs. They'll be combined if their usage is done at the same building and with the same materials.
Fish Dissector and Fish Cleaner -> Fish Preparer (or some such)
Animal Training and Animal Care -> Animal Caretaker
Wood Burner and Furnace Operator -> Furnace Operator (Let's face it, it doesn't take much skill to sit and watch wood being burned. Let the Furnace Operator, who can only operate 2 buildings in the "Furance" category anyways, handle it)
Gem Cutting and Gem Setting -> Gemcrafting
Architecture -> Keep it as toggle on/off, like Hauling, but don't allow people to become Building Designers if there's no use for it. Auto toggle on for certain professions, lik Carpentry and Masonry.
There are probably others out there I am forgetting, but I don't want to suggest consolidation for professions I don't have much experience with. I feel it's a small change that'll reduce some busy work and make for less useless migrants, in addition to just making logical sense.
