You're in no position to judge until you've played the game for a couple of months. No matter how much natural talent a person may have, it takes awhile to acquaint oneself with the intricacies of the game mechanics. And even then, I would go so far as to say that only regular duelists can tell. There's just no other way to truly familiarize yourself with the system.
When you know what swings are faster than others on the different weapon types, the difference in length between the swings on different weapons, the timing required for a perfect one-hand stab, what kind of foot work allows you to attack twice, and all the other little details- and know it well enough to react to it without thinking- that's when you'll realize that there are at there are little to no auto-block hackers out there. Most of them got caught, and all get caught eventually.
On top of it all, auto-blocking doesn't help you against experienced players. Unless you're truly bad at blocking, and those people are few and far between.
