Worrying about the lack of dynamic campaign in SH3, made sense. Worrying about... nothing in particular in SH5... is not very productive, for anybody.
Meh don't worry, SH5 will have the same scalability for realism as the others in the series. They won't do away with manual targeting, and no map contact updates etc... In fact I bet we'll see a few new 'realism' features.
See... glass half full, the best/only way to live life.
