This revision now requires changes to proceed.

Rather than using the RNG engine directly and using mod operations, the correct usage pattern is to use a distribution over the desired range and let it pull raw entropy out of the engine while mapping it into whatever distribution the use case requires.

See http://en.cppreference.com/w/cpp/numeric/random/uniform_int_distribution for more details.
