IMO, this is not a good idea, because most people tend to use faucet to try out the sites before playng with their deposit money, if people dont read this statement about different roll speed if you use faucet, people will think that the site is actually slow and will not leave a good impression for them
I agree with arallmuus, many people tried faucet first, if the speed is very fast, the site is everything OK for them, they will deposit money.
Take my example, when I use this site, it always shows: Socket Connection Failed. some features will not function!
In this situation, I wouldn't deposit because I am worried about the connection failed may influence my user experience, therefore I play with faucet money.
