I've noticed it, but don't mind it. I don't think it's a gameplay mechanics hiccup, and I think it was intentional, and that it works perfectly well.
Even some non-Mexicans / Spaniards have taken to using the term "
gringo". If one lives long enough in a foreign country, you usually acquire that region's
patois and mannerisms.
Also, the term "Outlander" among Outlanders might be considered one of fellowship... you're not from around here, we're not from around here, so we have something in common! Care to join us for a round?
No call for Dragon Breaks here.
