There are 3 buttons to press to dodge. (I just confused them, sorry).
The right combo is block+jump+direction.

Not everybody possesses your dexterity. To me, pressing those 3 buttons together while battling is impossible.
I can activate this silly combo if I have time to think my move. But while in combat it's not possible.

There are already some pages in here where ppl complain this combo is too difficult and other ppl answer "What ? No, it's easy".

So I mod my game, change keybinding for dogging and I'm happy.
