The day is close when Kaw becomes all spy builds. The time is coming. Convert now. But seriously kaw will eventually become all spys, ponder that thought.
As time goes on, and updates are added, the game mechanics will change. People will adapt to different style of plays. If the game turns into a spy game, something will be implemented to stop it by the devs. As of now, you can't do anything but go along with it. If you don't want to be a spy, don't be. You can still be an attack build. Spies are able to steal and not be seen. They give up being able to make money from allies though, unless they're a hansel.
