If there were no honorifics I would actually prefer the dub to the japanese voices. Ugh, Persona 3 was terrible too. JUUNPEEIKOON --- Now Playing: Ocarina of Time 3D, Pokemon White 2, Kid Icarus: Uprising. 3DS FC: 4167-5579-1461
I don't think I'd really care, but I do like when Rise calls me Senpai . . . . --- Blades will bleed. Shields will shatter. But as the light fades, will The Hero rise again? Or will Darkness reign? ~ Zelda TP Trailer 1
It would be much worse, it is set in japan so they should be used it adds a lot to the relationships and various cultural inflections. Part of the appeal of Persona to western audiences is the fact that it is a different culture.
If it wasnt set in japan the it would be ok to ditch them.
Consistent use of them however would have been great one way or another. The Mr. or Mis vs Sensei with the teachers, the -san in game then Yosuke's use of "Miss Amagi" in the quiz game, Big Bro vs Onii-chan (the latter is much more appropriate and not unusual for those even unrelated to use it)
