Wing Chun’s flaws?

There are 2 things that people say Wing Chun does not have:

1/ Head height kicks

2/ Grappling

1/ Firstly, kicking to the head is like trying to punch someone’s feet, why would you take your lowest weapon for your highest target?

2/ And secondly, grappling?  That IS Chi Sau!  The whole point of Chi Sau is to learn body mechanics, where thing bend and do not bend, these same principles work on the ground too, WE, just try not to go to the ground, because if there are 2 attackers you are screwed.
