I noticed that very very often the servers are down. Especially these days, I almost cannot connect. I think that they are doing this on purpose, to make us pay for the game eventually. It is impossible that servers are so often not working. Do you think they will start charging us for the game?
The servers problem is because a lot of people are interested in playing, especially when they hear the game is free. I am sure they will expand the capacity, but also I dont think they will start charging for playing the game. The basic game will always be free. Maybe it will come some expansion which you have to pay for.
