At this point you don't have to come up with a new idea, because every casinos have the same games and operational styles unless you are using a scam online casinos, now if a new casino rely want to satisfy users they need to stay on their words, and not make a living hell out of gamblers.
New casinos need to use better tech and certified operators, this days casinos are been run by less qualified personnel, if not why would they find it hard to use a popular KYC verification system or engine? Most online casinos will reject my national identity card but most times always accept only my drivers licence? Whereas on other KYC platforms they accept any form of identification as far as its real.
I think many gamblers also want this and I don't think all the casinos can grant our wish because that can only lead for them to collapse. As you said, many casinos have similarities, so they must actually try to be unique so that they can get noticed by the gamblers easily because these gamblers must be bored already from the usual thing that they are seeing every single day. Whether we like it or not, it's already a common thing to use some kind of sweet words, only to turn heads. See what we have here?
We are debating here, which means it is super effective. Like we said earlier, almost all casinos now have similarities, so new casinos just go with the flow. Gamblers can still accept this fact and they will still try to play on these casinos. Sorry to hear about your annoyance in the KYC system but I think all casinos uses the same KYC system. It's just that there are times that it can experience an issue, (you know, nothing in this world is perfect) and I believe that sometimes the issue is from within us, so patience is only needed here.
