100 Consecutive Wins Isn't Enough Skill Yet

Just the other day... I played the 100-win consecutive battle in Terry's Wonderland SP (TerryWonder SP), which you can only challenge once a day, for the first time in a while. As you can see in the image, I'm still far from 70 wins, and King Leo's 'Beast General' Leon stubbornly fought through most of the battles to secure victories. (Leon's specialty is a grueling fight.) This consecutive battle system apparently gets progressively harder with each win, and I really felt that this level of victory is still insufficient. (At 50 wins, all incapacitated members, including reserves, are fully healed, but if your skill isn't enough, you'll be defeated again, so I need to train them...) Next time I challenge, I'll train my members more. Who should I train? ...Just between us, you can earn far more gold by running the 'Good Dark Door' with the player skill 'Easy Exploration' every hour than by earning gold in the consecutive battle. I feel like the consecutive battle should be considered more of a post-game endurance test and skill-check element.
