What Darklink means is that all the missions are determined by the draw of the cards, be it 6 down, 2 up, 3 hidden etc. At the end of the day the victory conditions are the same for all maelstrom missions in that they are dependent on the cards you draw. Therefore the conclusions we are drawing about behaviour are applicable to all missions as the only changing significant variable is the way you draw the cards. Compared to the Eternal war missions where you need to have played them all as their own experiment, because the scouring and the relic have drastically different win conditions you cannot use one to draw conclusions about the other.
