Why is the random purchase timer up to 24 hours rather than 8-12 hours?

And the lottery is not gonna be as fabulous as you think. People are already getting angry not getting their drops against 7 other players in an instance spammable every 10 minutes. Now imagine it with hundreds of players to compete against, and having to wait several days between each try the rare times a plot become available again XD

I believe only those who can spend countless hours camping Placard would get mad about lotto system, while other players who prefer playing other content would welcome a system that give a much much wider inclusion despite the higher competition.
