Regarding unbalanced compensation

I believe the rewards for various events, such as live events and Champion Finals, in UT mode are very unbalanced. I think the current rewards for live events are fine, as they provide opportunities for people with limited time or who aren't very skilled to earn rewards. However, aren't the rewards for DR and CF disproportionate to the effort involved? How can the rewards for DR and CF, which take several hours and are mentally demanding, be the same as the rewards for live events that can be achieved in less than an hour? Shouldn't the rewards for DR, especially CF, be better? For example, the reward for 13 or more wins in CF should be a guaranteed high-rated event card that can't be obtained anywhere else. 15 wins should not be based on luck, but should guarantee the best possible result. Even with 5-6 wins, there should be no lower rating requirement, but an event card should be obtainable. If the rewards aren't such that participants are reasonably satisfied, then I don't see why they're putting in the time, effort, and stress of playing CF; it's not worth it. Playing CF, and striving to improve to achieve good results in CF, is wasted when the rewards are not rewarding. Shouldn't this be an issue that needs to be considered?
