The reason why grace periods are in other hunger games servers (with another plugin) is because in almost every chest in the cornucopia, you always get swords (it oftenly happens but sometimes 1-2 chests doesn't have 'em) In MCSG, the chests are properly organised, in dem other servers, terrible. So, if you add grace periods to the server, it slows down the game, even though 5 seconds, the game will get slower by 2+ minutes. So, I'd say, the day of adding grace periods, will be the day of pros crying (since if they get a sword, they can't go on a killing spree, every one does that)
