There's no racist like a liberal racist.
Anyways, this is more of a Japanese design issue than anything else. Mostly because:
Kind of. The Japanese have never felt like they belong with the rest of East Asia (cultural thing), so they design themselves like westerners. Because of this trend and it's evolution, nowadays it's common to see all Asian characters with large brown eyes, light hair, and pale, pink skins (and sometimes even ASIAN FUCKING REDHEADS). So how do you distinguish that from real westerners? Well, they use the only stereotype they know: Europeans are blond and blue eyed. This is why we get Danish-looking Greeks, Swedish-looking Frenchmen, and fucking German-looking Ottomans. Conversely, stereotyping of African characters gives us a Nigerian-looking North African.
So to answer OP's question: Japanese game designers can only make western-looking characters. As this series moves further away from its historical-stereotypes roots and closer to medieval fantasy (which is absurd, as this game takes place during the height of colonialism), you can expect even fewer non-European characters.
In summary, it's like fast food restaurants like McDonald's and Taco Bell. It serves you the "supposed" stuff, but don't question what you eat. Chances are they may not be authentic food.
