from the point of view of someone who has never cared about name origin enough to look anything up and can associate only the most obvious greek god ones and the like, "raynor" simply sounds better than those other two mentioned. and i like that i don't have to think for a few seconds on how to pronounce it when i look at the name. or worse, just completely guess and then have a small part of my own personal FS world come crashing down when it finally gets voice-acted. (bei was always pronounced like "by" in my head. and that little voice in there still screams over the VA to drown it out.)
