Hm, I have heard the FF fanbase called many things, but "hardened" has never been one of them. I don't think they really think or care about things like that unless it's a word that they feel really needs to be changed [ie, Bartz's name is supposed to be "Butz", which would be pronounced as "boots". However, it was changed to "Bartz" to prevent people from calling it "butts", although the shoddy fan translation kept the name as "Butz"].
