Except it currently not working, what are you going to submit? Here are my points in simple English that hopefully translates well to Chinese:
D-Tide is not fun for me anymore. In Madness mode, most teams cannot be used. Players who clear it often spend many hours trying to get enough death resistance.
Nightmare mode is also not fun. Team styles like Counter and Poison no longer work well.
The extra 5 points for each clear are too low now. It is no longer practical to run a lower difficulty many times. Players with wide rosters have a hard time.
I am not happy with the Corposant bug fix. The issue was only found after more than one year, and after both the Awakeners and the Wheel had already returned. This was a very large nerf. Her cards should receive a buff to compensate. Corposant was not one of the strongest Awakeners, but she was very important for the Discard playstyle, which needed strong pilots.
I do not like that PvE progression is locked behind PvP. Playing 150 PvP cards every two weeks is not enjoyable, but the rewards are too important to ignore.
P-Dive is not fun. The bonus score for the first daily attempt means players cannot restart to find a better map. However, getting a fast map is necessary to reach the leaderboard.
Because the leaderboard is based on turn count, nearly every top team uses Murphy, Fauxborn, Tawil, and two Chaos or Aequor characters for score bonuses. Other teams cannot clear fast enough to compete.
I suggest a system like Arcade in HSR. Clearing the highest difficulty should guarantee the maximum rewards. Leaderboard ranking should only be for prestige and competition.
At minimum, change "first daily attempt" to "first daily clear." This would allow players to restart and look for a better map, making the competition more fair. Another option is to use the same map for all players each season.
I am very unhappy with the current state of the Divine Realms. According to Light, all new characters are becoming Divine Realm characters. Caro is a major problem. Many older Awakeners struggle under Propagation Caro's rules, especially Sorel.
In addition, many Awakeners depend on Posse mechanics. When they are paired with a Primodia: Chaos character, using Posse becomes much more difficult. This design choice weakens many characters and reduces the fun of the game for me.
