Link to same question, no answers at that time either.
Apparently no one knows right now. We need a tech guru of some kind to look into it(if they haven't already).
EDIT: Oh yes, I meant to mention that yes, it has been proved that Assassin shadow masters/warrior's skills synergize each other(though in a round about way), so it is true that minion skills synergize each other. It may still be undetermined if merc skills do.
