Yes, only if they're in conflict. Because if they're not in conflict, how then are crafting Canim any kind of problem for Alerans?
Who cares if they are in conflict or not ?I think What belmonte is trying to say, is that furycraft is what keeps alerans balanced with the other races.
Canim - Longevity (uber-insane alone), (Blood Magic), (Compared to an aleran, strength = to a knight lvl earthcrafter )
Marat - No idea of their longevity probably longer then humans though, Bonding, and are physically superior to humans in every way.
Icemen - longevity is probably longer then humans, some kind of advanced form of watercrafting, physically superior to humans.
Humans - Without furycraft... (uhhhh........)
And if you add the furycraft to the other races...
my 2 cents.
Although, in the grand scheme of things if the races of carna want to survive then its probably a good idea.
