I did my first GNW yesterday on a fairly new server, and we had a total of 19 people in our fights overall.
But finding out who got what packs, was not hard, and it was fair.
And next week, the people that got packs will automaticly recive a lower chance of getting one, so that it rotates to everyone, and not just the strong one.
What system do you have to determine who gets what?
