ok, to answer your questions in order
1. yes, this is a forum you can question anything
2. yes, you can say anything you want in the forums as long as you do not violate the ToS. just be ready for in game responses in addition to replies on the forums
3. yes, if feelings are not considered evidence then why are we all even posting here because everything said here is based on feelings.
4. well first off a discussion cannot become a war until it spills over into the game. a war is a game mechanic and since these are questions about the meta game, this forum is part of the meta game, hence anything you do here can be replied to in game, that is what makes it a "meta game" instead of just a game. and no they cannot censor anyone that is willing to be razed back to the newb ring because someone willing to be razed back is willing to accept the consequences of what they say and can say anything they want.
btw these are my opinions and based on my feelings so if you dont agree with my answer to number 3 then just ignore this post and anything i say from here on.
