If 60% of my army is alive and I have to find a different target, I have options. If the retal is there it is essentially a guaranteed win. Are there other tactics people could use to take counter someone being on QR? Absolutely. That is called strategy.
I’ve been smashed on QR and still lost 100% of my defending army so I came out with 36% and 24 hours to retrain as much as possible.
My hunch is today the majority of retals are taken and successful. I think I’ve had one person bounce on their retal and he tried knowing he had no shot, but it weakened me which was a good thing for his alliance.
The BF penalty hurts, it helps the smaller kingdom. Forces larger kingdoms to commit more of their army which opens up the door to the retal.
The situation to address though is breaking extremely large kingdoms who sit on QR because it is their best defensive strategy to bounce attackers. When you know you overpower the enemy, sit on QR so they kill less. You’re still going to kill a ton because you are stronger than they are.
