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.
Yes all market is full of competition and we be aware that is what make a casino to do better than the other since they can easily go through their counterpart and improve more so that gamblers will be able to keep using them since everyone is looking out for the best casino where they will get mostly 90% of what they want to do with having to go through stress or customer care service.
