I think the new system could be more like the old system if the defaults made a little more sense. Back in the DF of yore, you assigned guys to a squad and what did they do?
Kill things when you asked them to, and train when you didn't, and nothing else.
That should be the default settings until someone goes in there and changes them to have their caravan patrol and cavern patrol and carnival patrol and all other patrols made up of words with 'c', 'a', 'v', 'r' and 'n'. I've fiddled around with my stupid settings over and over again and what do I have now? A squad that:
Kills things when I ask them to and dicks around endlessly otherwise, oftentimes taking their armor off or otherwise doing things that slow them down when I ask them to kill something, or continuously arranging and waiting for training that never happens (except for the guy who's doing individual combat drills, which has made him a Novice Armor User after 4 years). I don't want to get cheap champions like the good old days but I'd like my stupid dwarfs to not consider the military life to be wine and oysters (or starvation when on duty). I love the new kill command and the move command, but otherwise, the whole thing is requiring way too much effort for what most people want it to do, and assumably that functionality is there, but just not by default.
Now, I know that I'm not doing it right (and that there are probably little bugs) but why the heck don't the default settings resemble old DF? Why would I want to create a squad of military idjits and then have to manually tweak settings so that they do, for the most part, is what they were doing back in the good old days?
