I think that because many practitioners do NOT like to fight that many teachers have passed off chi sao as all that is need ( along with some drills).
People get really good a chi sao and don't like doing hard sparring.
I know that it isn't a common phenomena in BJJ BUt I do know of a few guys that just roll ( only ground work) and don't like to spar or anything that takes them outside their comfort zone.
What happens is that we get so good and enjoy being good at a safe and limited skill set that we simply choose not to believe that we need to actually get hit and hit in training.
It isn't just WC either, I know many a kyokushin guy that can't fight with head shots as well as they can without so all they focus on is no-headshots sparring and then make themselves believe that it is enough.
