Its not so much "the strike".
Its the flurry of strikes...alternating hooks as mentioned above...RLRLRLRLR and the inability to get up any kind of a defense up against it.
I do agree that at times you can correctly parry or block that immediate single big shot that some try and get off right as you get up. Actually I think that exploit is much improved post patch but the barrage of RLRLRLRL is something new and completely different.
