Even if people kept their dicing using hax they are untradeable and can't be rolled anymore. People play horse games, flower games, and IRC dicing now. So dicing as you refer to it IS dead, but gambling is not.
Dicing ingame is over but now you can do irc dicing or horse game...people seem to have died down on flower game though i was trying to host but nobody wanted to play
I don't think dicing is dead just yet, but its definitely not nearly as possible as it used to be. I don't think the IRC dicing will catch on the same way dicing ingame did either.
