Yes it is and unfortunately we have to do it - so do others sites. It cannot be the same bet speed for a user that is just using the faucet and a user who is depositing his own money. Obviously Da Dice is a business and we have in the first instance to use server resources for users who deposited with us. I will find out with dev what kind of threshold is applied.
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
