For all of you fellas who are having trouble without DT I want to share with you a little challenge that I've had quite a bit of fun with in the past. It is simple: turn on all labors for all dwarves. It sounds crazy hectic, but there are many tools in the game that previously you may have largely ignored because of the comforts of DT. Organizing your jobs, using workshop profiles, and learning to use smaller more strategic designations and orders can make your output much stronger.
I can see that working with certain jobs (I like to have hordes of untrained masons for fast walls/floors myself), but absolutely not with other. Turning on mining for all dwarves doesn't seem like it's ever going to end well, since skill is so vastly important for that job.
Actually, if you just have 2-3 picks, the dwarves will never put them down and only those three will train. At least I think thats how it works. Or, you know, just let 50 untrained dwarves smash into rocks. That works well too.
I usually have a few jobs I specify, near constant demand skills that basically would assure nobody would get anything else done, Mining, Woodcutting, Hunting, FISHING (dwarves would ALWAYS rather be fishing), plant gathering, and sometimes hauling are the only skills I really change. That said, changing labors is far more painless than I remember it being and later on with more migrants, you can almost just let the migrants do whatever labors they come with creating jobs based upon their skills. When it comes to professions, you can have one unassigned workshop dedicated to "get this done now" and then another workshop assigned to a specific dwarf who is a professional. Another strategy I had considered was making my original 7 be the "every labor" dwarves then let migrants take up their jobs as they come in.
