Please please please STOP with the pairing algorhythms and the obvious cheating that Arena does. Just give us random pairings by rank - thats it - no further manipulations. Let us draw cards randomly as you can with a computer and let actual skill determine who wins and not your obvious manipulations. What you are doing is reprehensible to a competitive player. The game is good if you would just stop the behind the scenes manipulation of what is happening.
