Tus is dieing, but wa's activity is not bad in my opinion. The new players just dont know about this community. Tus was made and handed by oldschoolers, but you can't expect that they will do this forever. You just come here and complain about things, but you don't do anything in order to help making it better, keeping it alive, because you are used to that you don't need to do anything if you would like to have something good, because you get everything from the internet ready. If you don't like something or you just got bored of it then you won't try to make it better, you will search for another game (ready product). So in my opinion there are really a few guys of the new generation who are not lazy to do something which isn't so much convenient.
(Ps. "You" means tnelguys from the new generation, not only you ^^)
