I think the War bonuses are too much. All things being equal, someone fighting a player from the winning War team has to get first in the duel phase and the winning War player has to get last for the challenger to actually win in the Trials. I know when I went against kevkev in the Fire Trials last time it was actually impossible for me to win the Trials because of the War bonus. This discourages people from challenging the winning element from the War due to too great a disadvantage.
I think the War bonuses should be reduced to 4, 3, 2, and 1 for the top 4 teams. I also think the points for dueling should be increased to match the Masters points (14, 10, 6, 2). This would make the dueling phase the most important and increase the epicness of battles.
