Mauls are not very slow indeed, if you block, most of the time you can land a hit with a sideswing if you hit at a short angle (a basic block can stop that ofc). You must take in consideration though that that vid is made from around 30 minutes or more recorded material, so the best hits are in there. The fights where i blocked, tried to hit someone but was too slow and got killed are not in there ofc.
