They should make a new game mode like arena only your entire hero deck fights 5 at a time until one side it defeated. Also we get to arrange each group of 5 and in what order they go into battle. This would be with GW rules where health and turns carry over from previous fight. This would be epic and encourage people to collect and level toons as they all can help in the war and not just sit around. Then there would be rewards added up for your rank.
