The most important is to be in the next CH.L. , so now you 're out (with 5th position) .
About opponents, some times we think that we 're better in q so why not set attack.
But many times you 're losing if oppo can defend his posts and his counter attacks are going well.
Why don't you try also to play defense/counter vs weaker teams, to see how it works.

Also if you have many players for rotation, try to find those who are performing better in the league than in CH.L., use them and use the others for CH.L.
If you have strong friends and you 're playing together in the league, "unfriend" them last Saturday, before the new season.
