Perhaps they intend to learn. You can't learn top warring from war tier. If Jesters fight hard and push enough with what they know they might see things they've not seen before.
Sadly, many kingdoms subject to pulverizing forget what's important and chalk things up to fairytales. You dissect every piece of intel you gather at this time. Should've been recording everything leading up.
Reaction time
Activity
Pump
Strat switches
Intel for distribution/SN for resource movement
At the same time, if Jesters were willing to take the initiative to attack then they should've also been aware of dictating pace. Even in a losing scenario it's important to strike first where things are soft. If you're not, you start. And don't stick to the same boring strategy that every war kingdom that loses to the best stick to. Change things up and don't micromanage anything but information. Like football you should be at a level where you run no huddle silent count.
Have fun and make use of this war.
