Does not need to be separated, just have us create a 4th character for PVP only and have a new tier in the crucible for serious competitive PVP. New character and subclass would be PVP only. That way we get it all, still have the game we know and love to play and the hardcore PVP get a totally balanced and highly competitive hardcore mode. This is the only way to keep the constant nerf's from seriously impacting PVE and stop the complaints over balance. It is a very simple solution, especially after we have seen what the live team can do.
