This screenshot is from February of this year when I was a lower level. That almost 32k power line won against the 253k power line. I used Fast Forward for the first attack. Surprised I tried again with a regular attack and watched my line get pulverized. They stood absolutely zero chance of winning. Then I tried one more time again on Fast Forward, and they won again.
If anything is found, I bet it has to do with how Fast Forward works. The only time I was able to beat high level players was when I was near their promotion level even though they had higher levels, and/or they had bad runes, or bad team compositions.
Overall your runes are above the average player, and your compositions look strong for S11, and your promotion levels are also good. My only guess is that it has to do with how Fast Forward works, some kind of error that is allowing them to win all 3 attacks.
Edit: It came to my attention I meant to say Quick Fight and not Fast Forward, the feature where you use the raid ticket.
