Gathering global timers have to go... Personal Cooldowns for nodes.
That every gatherer has to be on the same node at the same time for lore reasons make no sense at all. Not only that, really hurts how players distribute their game time, instead of this unspoiled node non-sense of global timers forced into the players using the eorzean day/night cycle.
Just give each player a personal timer, so each player can go and gather when they want and not when the game wants them to, with a personal timer for those nodes in place, nothing can be abused since players will gather the exact same amount of items on the same time windows, only diference, now they will decide which time they do that.
