There are good and less good sides in all forums. Nothing is perfect because it is free and made by fans. I enjoy chinese forums because they are very passionate about WoG and very curious about what is being done with. I am sure that if your Phenix mod was translated in english, they would start translate it in chinese and you will get thousands replies about it. I have no problems translating it with Google. Language is often a barrier but with a bit of effort from both sides it can be aborted.
I would say actually there are 2 big active forums, the russian from forum.df2.ru and the chinese. Heroes community is an insult to WoG or Heroes. I enjoy too this one, however too little users registered.
