Again never suggested that someone not learn to grapple....
To be honest though one person has inferred that you don't need grappling.
your over complicating it, hit them, kick them elbow them and knee them, don't grapple with them once they realise that trying to grab your legs or arm is a very painful experience they will stop it
I don't need to, I punch people and they generaly fall over, if that doesn't work I hit them again if it gets up close I grab their Adams apple till they pass out
wrestling is alright for fat blokes that can't punch
