I experienced the same last season. 130q vs 50 lost 0-1. No one attended. Have 4 attackers with over 200 attack rating but their 4 star defenders outplayed them. I thought it might have been my formation so I checked against counter formations and it wasn't that either. Had only 1 attacker rated above 7 that match. My personal opinion is there are some matches they just want us to lose. Or perhaps I needed to attend that particular match to win. Depends on what criteria the engine decides will be the match winner. Could be win bonus, could be morale?
