The only reason for this is because of the points system, a ladder should never get reset, although it's too late now.
With a ladder points system you would get more points for playing stronger teams, we don't even need divisions, any1 can play any1 who isn't more than 5 places above or below them, also with thistype of system you could climb up the ladder quicker and teams won't be forced to play teams a lot better than them as much since these higher teams would rather play teams with more points.
Or there is the league system where every1 plays every1 in the whole divsion with a 3-1-0 points system.
IT sucks no matter who wins the league if it comes down to who played who in what order.
And don't say I'm taking this too seriously, my point is what is the point of a 1st place if it doesn't represent who beat who ?
