I could personally do without the honorifics as well.
I'm all for retaining the spirit of the original game, but as I played through P4 I realized that I never even payed them much attention. They just kind of seem annoying after a while, hearing them spoken out in English just doesn't sit right. Most of the time I was able to parse out how the characters viewed each other through the actual performances. Kanji usually sounded pretty excited when talking to Yu, and you could tell when someone was teasing another character, etc. I didn't need the senpai's and kuns added on there.
I dunno, it's something I expected to be fine with going in, but coming out I realized that they just didn't seem necessary.
