Make sure you're using the terms correctly. A lot of animals have been tamed, without being domesticated. Domesticated animals are rare. Large and useful domesticated animals even rarer. Jared Diamond's Guns, Germs and Steel describes the difference. People have been attempting to domesticate some species for decades, without success. Now, magic may make a difference, but in a world where there are deities that like nature in its wild state that would probably come with a risk.
Arguably in a world of active deities, spellcasting mortals capable of destroying significant parts of armies, and strange monsters, things do get really silly if you just slap those things on top of a normal medieval society. Considering how reliable magic is, it either has to be incredibly rare or the effect on the economies is going to be marked. Depending, of course, on what magic is allowed to do.
BTW, I think the term is being misused. I think they're suggesting you can tame a hippogriff, and using the terminology incorrectly. I certainly don't believe in hippogriff farms.
Ok, totally not a natural sciences kind of guy. To me, tamed and domesticated are pretty much the same thing. If you can raise it, train it, and then breed it, it's domesticated as far as I'm concerned.
See, these conversations go pretty much exactly the same way. If people want faux Europe, then fair enough. They've had their way with D&D for thirty years. Every baseline setting is Middle Earth with a bit more magic.
I just find it stretches my suspension of disbelief when every attempt to bring in any sort of consequence to the setting based on what's in the rule books is automatically doomed to failure simply because it doesn't fit the archetype.
I'd much rather either change the rules so they DO fit the archetype, or pick a new archetype.
I mean, look at hippogriffs. We can take their eggs, they'll hatch without the mothers (since you can sell the eggs, it's pretty obvious they'll hatch), you can train them to do all sorts of things, including carry riders. But, somehow, they refuse to breed in captivity.
And this same thing is true of EVERY SINGLE creature in the Monster Manual. In a setting where you can actually change reality with a WISH, no one in the history of the setting has figured out how to breed creatures.
I just wish there was a setting or two out there that actually took D&D concepts into account. Eberron goes a long way towards this, although I think they didn't go far enough.
