I have anxiety about missing stuff in games. Batman has the problem of making me want to use his vision mode all the time and in Dragon Age Inquisition I made a macro that automatically used the ping at all times so I wouldn't miss anything. Answers should make this game much easier to enjoy because at the moment I'm walking around slowly with the scanner open most of the time.
When should I be bringing up the scanner? is there any indication when there are things to scan for research points? Are they just scattered through environments throughout? Are there sections where i can be sure there is nothing to scan?
