you should add faucet
it will attract a lot of people!!!
IMO their bankroll is much too small to support a faucet. The max bet for what their bankroll (~11 BTC currently) can support is only a little bit larger then what faucets would give out. Plus you have the issue of the fact that the bankroll is investor funded
An alternate suggestion would be to allow people to play with "play" money that cannot be withdrawn and is kept track of separately then real bitcoin deposited.
this also a good suggestion because there are dice sites that has no faucet but was able to get supportive members
