Dunno, man. Targetting with the analog stick was never a hassle at all. Granted, mouselook could make camera turning faster and smoother, but I'll stick to the precise controls (as far as movement goes) of the analog, specially in those narrow places.
Nah, I respect mouse + kb combo and it's probably a controller scheme you're more accustomed to, but I've never found it to be a win-all solution for any game. Some controller types work best for certain genres/games and others you're just more used to a certain control type.
But again, I do hope Fromsoftware does give us choice and I'll be happy.
