As per the patch notes: http://na.finalfantasyxiv.com/lodest...1f30e41d038115

The /random text command has been added, allowing players to randomly generate numbers in the log window.
/random is coming, and casinos are going to happen. There will be players that both love and hate it, this much is known. But what will be SEs stance on the matter? Will it be allowed? Will it break the ToS? What's your opinion on the matter?
