Well, the people are getting more experienced these days, and some of them read the threads which are already there. As example when I was starting to play the game I was reading tons of threads and I was also asking about how to beat some formations, just like the other new players. I think that the game is getting more and more inactive these days, I don't think that there are as many people joining the game anymore as a few months ago.

Now that I've got some experience in the game and know how to beat several formations I'm getting more and more inactive on the forums too.
