I really enjoyed the NA Haurchefant, but the JP one is also hilarious and amazing too. It's a shame he was different, I don't think FFXIV needs to be worried about having odd/strange characters (your audience is hardly conservative - think of all the strange and odd things that have been accepted in previous Final Fantasy games).
Either way, I still think you did a great job! Don't take this upon yourself too harshly. It would be interesting to know why his behaviour was seen as problematic in the first place though. Was there concerns that players would be bothered by implying homosexual interest (hopefully not, because that would be pretty sad if that were the case)?
