I
choose blacksmith but i realy dont know why
Quite frankly, I think most will.
The usefulness of the different classes pretty much boils down to
nugget spender, or non nugget spender.
The different craftmanships is pretty much a substitute for nuggets, with a few exceptions. I think the variety of the classes will vary allot more on non prem worlds.
Here is my conclusion. You can all make up your own minds about this.
Field cook
The Field cook is able to cook a delicious meal from almost anything he finds in the wilderness, giving you power for the whole day.
(Skill Point & Labour Point Booster, for the times you really need to be able to do that special job or quest.)
Conclusion: Not completely useless, but not far from it..
Tonic Peddler
The charlatan experiments with everything he has and sells the outcome as potions and other tonics.
(Work & Dueling Motivation, Health & Energy Boost)
Conclusion: Great for those that can't wait 4 hours for full health and energy, or thinks this will enable them to work the same job 24/7. HP potions WILL be on high demand, so here is a chance to make some money.
Blacksmith
The Blacksmith specialises(<-typo by Inno) in working metal to form usable items and improve tools and weapons.
(Bonus to damage in fort battles & duels)
Conclusion: Might just be enough to give you an advantage. A worthwhile profession, with items that will sell on the market.
Master Saddler
The Master saddler is an expert in leather and wood work. The products of his profession help you to minimise the strenuosity of travelling and make life generally more comfortable.
(Mainly about traveling speed, with some boosts to work motivation & energy.)
Conclusion: A pretty boring class. Most use nuggets for fast speed anyhow, and if you want to increase your work motivation, pick the Tonic Peddler Class.
