can't block throws?

How to block throws?

Hold left mouse button, and u might get luck to have the thrower run out of energy and not throw u. Holding the left mouse button slows down the charge for throwing, so the thrower uses up more energy to charge the throw.

I think hes talking about when the block gets thrown into you.

A mass in motion stays in motion etc.
It just cant be blocked

The only way to stop, is when the person is bieng twisted, to have him resist as told above and hope the enemy runs out of ki.
