2 bad its not 6 matches where you play all 3 opponents twice (champions league style) and then can revenge your lost on an early round. also a bit longer season wouldn't hurt considering there are only 2 ICTF leagues a year. don't like that cross divisional matches which are usually unfair to some teams and for others just great...
Leagues tend to work better(my opinion) when it's shorter. I like to keep playing with new players. Playing with someone for 6weeks(2months at most) would make me hate a person :p
