I'm not sure if this is a bug, or if I just don't understand the scoring metric in the new Coliseum event. When I attack the boss, I seem to get one wave that affects the boss's health and percent defeat, then it sticks and I only increase my total score by 1 with each subsequent attack until he kills me. For example, I was able to defeat the first tier on my first attack, having done massive damage to reach 100% defeat; in tier 2, I hit hard on go 1, got 60% damage, but then it stuck at 60% no matter how many times I hit him after that and how long I kept my guys alive. I understand the boss gets stronger as my score goes up, but I should be doing at least some damage in subsequent attacks.
Perhaps a more detailed explanation of scoring metrics would be helpful. I've searched online and scoured the forums, but I haven't found anything explaining this issue.
