Welcome to the forum; I just went through your post, and we can't say it is becoming a copycat.
As you know, the market competition situation and user trends are based on the likes and dislikes of the users.
Casinos must have to incorporate the features and offers, unlike other casinos. Adopting new requirements and trends is mandatory to attract new users and retain them.
More important is how the casino site can provide good service to its customers so they can be satisfied with its performance.
And although the casino site looks similar to other casinos, as long as the casino can provide satisfactory service to its members, it will not be a problem for the members.
They won't think about how it looks but how the casino can work well and not do anything bad or even cheat its members.
And this will be a healthy competition between casino sites where they must be able to provide the best for their members.
