just 2 explain:
-dwrves should be in places with a lot of mountains hence Iceland, Iberia and Norwegian and mediterranean regions. Although Ireland and Scotland could host dwarvs because of their speech accent.
-draenei seem to have a very eastern europe feel to them, like baltic accent and their culturally evolved.
-humans are definitely north american guys, no chance of being anywhere else.
-trolls belong in the jungles of Africa
-orcs are more north Africa up till Iraque because I feel they share the same ruthlessness towards rules but still are a very loyal people. And the harshness of the place seems like Orgrimmar right? <not to mention the obvious analogy between eastern and western societies with orcs and humans>
-tauren could be put in the planes of western south americas because of the lush planes and there are a lot of cattle there in reality.
-goblins just seemed like the mexican and panamenan style of people. Untrustworthy and with a lot of scraps left by richer countries.
-Nelves to me look like indians because of the tatoos and dark skin õ_õ
-Belves are mainly russian since they are light skinned, blue eyed and blonde.
-pandaren=china
-worgen should be obviously from London and French because of the uptight clothing and early 18th century groove
-forsaken are like the Romanian and Transylvanian and could live around those parts
-Gnomes are just the most prolific races so I see them like German or any other german speaking countries like switzerland, luxembourg.
