I think the thing that breaks the stealth rules is allowing passive checks for free (except when an opponent is on guard but I think technically being on guard is actually holding the search action?). I sort of approve of DC15 to stealth as a starting point. It makes group checks in heavy armour achievable with a bit of investment but quite tricky.
Why they are trying to make the invisible condition equivalent to the hidden condition? You can be invisible (cannot be targeted by spells) but not hidden (e.g. heard, smelled, felt).
