In computer science pure randomness does not exist. It is emulated with random number generator (RNG) engines whose performances can be very good or very bad, depending on how it is initialized, implemented, etc.
For instance, a badly initialized RNG engine will draw numbers that are NOT random at ALL and can even be PREDICTED.

After this MASSIVE screw up that we are witnessing on the housing system, I believe the player base have the right to know HOW the "fairness" of the system was actually enforced by Square Enix in FFXIV.

We want to know :
- what RNG engine did SE choose (at the very least Mersenne Twister??)
- how the engine was seeded
- a graph of the distribution of the engine actually picking 1B numbers : show the variance and the standard deviation.
- we also want the actual result of the lottery (all the tickets that were drawn) to prove the lottery was fair (graph of distribution, var and std)

As far as I'm concerned, I do not believe the system was fair seeing how it was buggy. I think I'm not alone in this case.

tl;dr: I want PROOF OF FAIRNESS OR ROLLBACK.
