I cant fully agree if disabling faucet can affect the site negatively. The faucet amount is just so small amount while users can earn much more through the rainbot, challenge, forum rewards, and many other promotions. Real gamblers wont really care about faucet in general imho so I think it is OK to remove the faucet.
Maybe they're spending so much on faucets that it's reducing their profits and those amounts could be spent on something better (ads contests,etc) . I also think it's reasonable for them to remove the faucet because the main reason for it is to play without a deposit and we can still do it since they don't have a minimum amount in all of their games. With that said, their faucet becomes a bonus and unncessary.
