my personal opinion : as customer & with my career as System Developer/DBA

In case I'm operate the PrimeDice.

I will bring back PD2 , but make it a little upgrade to be PD2.5 (or whatever)

- change the roll randomizer seed pair to be same as PD3 (able to change server seed pair at any moment)
- upgrade server to let it able to handle more load.
- introduce deposit/withdraw transaction history.

Make PD3 an official public beta until it's 100% functional.

It's known thing that transition period not always smooth.
But PD3 is far too rough transition. Keep down like this will bring site's reputation down.

Cheers!!
