I remember primedice, it was the first crypto dice site that I played with. And really impressive that they sustain their presence in the crypto market, where most of its contemporaries exited when btc took a downward tun. So with their long experience in the gambling industry, they really do know how to keep their players happy and they applied it to stake as well. Not a high roller, so didn't experience most of what the OP described. But it is a good insight coming from a high roller's perspectives.
Well, I know that we all have different preferences in terms of gambling experience and we choose those site that we feel and think that safeguard us. Some also had a bad experience to any of them makes them think about leaving and finding a new one better and maybe that OP has that kind of experience.
