Yes, it is fun to read how some teams that have never won anything believe that they have a priceless secret.
I've learned from both of them several years ago, so it was not a priceless secret. They talked about it on the forum, I've just read their posts and said to myself "ok, let's try to build a team that way".
Now my team is build, I'm ranked top 5 WR since a long time now (even If I've no chance to win B3) and I have 3 titles in a row in my country (the level is high in our country if we compare WR & recent results in B3). I'm only in the middle of my good team period so I'll probably add more titles.
So you can definitly win something with a good 3-2 zone.
