Actually I think HalberKill is closer to the truth on this, particularly since the Wiki back him up at least partially (they say 5 claws is closer to royalty):https://en.wikipedia.org/wiki/Chinese_dragon
this troll on WOW has the relevant bit: http://us.battle.net/wow/en/forum/topic ... 332?page=1
To be honest Strawhat, this claw count equals country thing seems to me more like a translation error made by some Western scholars/observers who probably thought that on the Asian dragons claw number tells you what nation they come from when the number actually meant that the dragon you are looking at was the exclusive symbol the royal house of the nation you are standing in (I can vouch that in Korea the 4 clawed dragon was worn exclusively by the royal family and the wiki states its clearly 5 for the Chinese Imperial family, Wouldn't be surprised if 3 claw exclusively represents the holy line of the mikados in Japan).
Plus all the claw types were present in this article about 2012 Korean new years festivities:http://blog.korea.net/?p=6629
If the claw thing were a real difference in the nationality of the dragon like you say, than all the dragons in that article would have had four claws because that fact would have been literally beaten into every last Korean since their childhood, (they are more than super nationalistic enough that they would make a big deal out of something like that, don't kid yourself).
Also Strawhat saying that you can only love dragons if you know about this dubious and obscure "the number of claws on Asian dragon tells you what nation it come from" rule is an odd thing to state so vehemently given that we are talking about a fantastical category beasts that very so greatly in appearance that it is not by nation so much as by the story that the description changes even in Asia (and I say that as someone who has been studying dragons in earnest since childhood), it is sort of like saying you can only be a true sports fan if you know the difference between the cleats worn in rugby, football, and soccer based on the number spikes or shoe lace holes.
