Except for one slight problem with all that. It is not about separating what we say on the forums and bringing it to the game. It IS about leaving arguements here in the forums where they belong and not bringing arguements to the game. You and others might not want to leave arguements here in the forum where they belong, that is you. Most people do in fact leave their arguements here on the forums and will quest/raid with the very people they argue with here without issue.
If you and others have issues letting arguements here, stay here and want to carry on with childish behavior with the person you were argueing here to bring that arguement to the game, what does that say about these people? Also, it is one thing for a person to admit they will bring that arguement into the game, it is another for them to suggest they won't when they have no intention to honor that and fully intend to bring it to the game when they suggested they wouldn't.
I think most people when they get into the game, want to actually play the game. Not carry on an arguement with someone from the forums instead. It is not such a hard concept to understand or agree to.
