Well I don't think anyone hacks on NA in any form from what I can see. If they do then they are pretty bad.
The notion of an autoblocker bot being better than a human is actually funny to me anyways, an autoblocking kid would never be able to attack properly and would never chamber or do anything fancy. They'd be worse than a real player.
Besides if you can't last 2 minutes without getting hit once in single player sparring vs a companion (ai set to good, speed on fastest) then you can't last in a duel in CRPG for more than 10 seconds.
Just like how you can train yourself to chamber every hit in a spar like a normal block, only to go into crpg and die to every held attack thrown at you. People are just really complex organic machines
.
Oh, and humans can predict better on leads than an aimbot. After watching a player for a second or so to see a few dodges, you can often see a loose pattern and shoot where they're going to be. It's easy but since it is not an actual solid pattern even a complex bot won't pick it up and will just blind lead. However, the majority of players are so mind numb they won't even bother predicting -.- "lol xd just spam"
