Master strike seems fun at start, but it ruins the combat, the combo are practically useless because you can't finish the combos. If the enemy do a master strike, you can't block, the same is for you, the enemy can't block your master strike. So, the combat can be kind of ridiculous, you just need to wait for the enemey to atack first. I killed a group of 5 enemies in a row just by doing a master strike, the last one I tried to atack with some combo, and the enemy did a master strike and hit me. When he tried to atack me again, I did a master strike and killed him. And that is the resume of the combat? It's a shame... The game already have some good mechanics of defense, like jump aside to evade the atack, normal block, perfect block, etc. But master strike it's just a script behaviour that does not require your skill, just press a single button...
