I really don't care if people save scum in a single player game, it doesn't affect me. They aren't trying to force it on us as a game mechanic, it is only a matter of player preference. Only time I do it is if an outcome is bugged or makes no sense, otherwise I prefer to keep playing even if something I don't like happens. All they need to do is have an option for people to turn it off if they want.
I think in EA there is a lot more of this since people are trying to see different outcomes, once released there will be less of it. They should take this into account with balancing some things that may not need balancing.
