I think it's unnecessary and I won't be using the feature. that being said, I'm not against it.
My only gripe is that it will probably be forced. Hopefully that won't be the case, though. Fingers crossed.
Also, too many people have been bitching about how FE:FAtes is "pandering to animefags and pedophiles", but you won't hear anyone say that the game is pandering to the queer community.
But that's none of my business.
