Yeah.... But why is it that a simple concept such as this has to raise so much crap. Animal men as civ members.
Good: Severe cave adaptated dorfs can send the animalmen to fight on the surface with those dorfs who won't leave a trail of vomit. They also have the size that dorfs don't have to make hunting easier for them, so they'd probably make good hunters. Animalmen benefit from the tools, food, and shelter they get from the dwarves. In turn, the dwarves also keep the bad stuff underground where it belongs.... usually...
Bad: Of course they'd be a hamper on resources, and you'd need to cater to their needs for housing and such too, making capturing/integrating trogs, animalmen and such an optional choice. But if someone wants more hands, and they accidently picked a dead civ, and new workers are N years away from adulthood, these individuals can provide a base to work with, taking up the slack for the lack of dwarves, and still retaining the benefits.
There's also (potentially in the future) To simply tell them to piss off or they may choose to leave on thier own if things go to shit, deciding the relationship isn't working. And the mortality rate was more based off player actions, as I was assuming this all under fortress mode play with say, civ possesing no -men to dump on your head. Cause there's still the xenophobia/philia/player decides option to the raws, if that's possible.
I'm still drawing from my own cheaty way of accomplishing this that showed animal men can be extremly useful to a fortress. Antmen for example, will defend the fortress with thier lives regardless if they're soldiers or not. Had one keep on choppin' trees till the giant badger actually went to tear her apart. No cancelation, just that they died. Found a giant badger foot, tow teeth and a decapitated antman. tigermen make great soldiers, due to thier size and strength compared to a dorf and haulers. And best of all, as civ members if the dwarves are killed, you can use the animal men to hold the fort until more arrive, if the civ isn't dead. And in terms of connections, they segregat themselves anyway, only socializing among themselves, reducing the tantrum impact: Dwarves don't care if the antmen die, antmen don't care if tigermen die, tigermen don't care if dorfs die. And yet they all work for the betterment of the fortress (or more the insane overseer running it's amusment.) They will get upset as thier fellows fall however.
And thus there are my view. Likely to be countered with matters of ethics, heirarchy and other crap when this is simply something players would like to have if they want to have the option to put a nusiance/threat to direct use for the fortress. Since many a DF players blatently disregard morality anyway cause they wanna have fun. Remeber those merperson concentration camps? Rabbitman population problem? Send'em here! We'll take good care of that little issue...... [AKA if there are still dorfs, they'll be happy to do as the overseer says: Magam sauna for all visiting rabbitmen.]
Sorry if I ruffled any feathers, Just wanted to get that rambling/justification out. I doubt strongly Toady will ever implement this anyway. But we all want to at least be heard.
