So everyone complains about nerves but why not instead just match problematic decks versus each other until the community naturally gravitates towards other play styles? Personally I think the psychology behind the matching system deserves a fresh look. I also think blizzard should be more transparent about what factors are considered when matching opponents.
One of the most glaring oversights I believe is an assessment of average time taken per turn. If powerful card mechanics required more thought and problem solving to the effective I think people would have less issue with card mechanics feeling busted!
