Button mapping would've been a welcoming addition, R2/L2 shouldn't be used so much, at least for me. I'm using the classic as well but it's taking some time for me to get used to, particularly changing the weapons since for a game that has an intense pace you've got to be quick, so it's a bit overwhelming having many buttons to take notice of. I didn't get to play long since I just tried the single-player section, kept getting the error message for the multiplayer but I'll play more when I have the time.
