3. I agree with posters above that a small faucet, even just 20 sats per 5 minutes, 10 claims per day, wouldn't hurt (of course, if you know a way of preventing abuse).
Again, it has been discussed many times previously. It is impossible to have faucet if the site do not reduce the minimum bet. Even 5000 satoshi faucet will be useless because the minimum bet is 25k satoshi.
I cannot understand why Rocketpot does not decrease the amount of minimum bet. It's in favor of gamblers and also Rocketpot.
If the minimum bet is lower, some new players will play in the website, then if they are interested they play with higher bets. Some cannot afford to bet 0.25 mBTC.
